- It's been 10,000 miles on the hybrid turbo swap and one year. Here are a few thoughts on this upgrade one year later.
Note when I said that other higher HP turbo upgrade options for this car will run you $10,000+ I was talking about the turbo kit itself plus all the bolt-ons, tune, tires and associated stuff that must be added to a high horsepower setup to make it complete. Go check the prices, it's crazy how much it can add up to in order to do it right. That's the cost of high horsepower. As I mentioned in the vid my setup runs around $2-$3,000 depending on what you get, new/used, if you install it yourself.
Thanks for watching, holler at me if you have questions. - วิทยาศาสตร์และเทคโนโลยี

Thanks. Your videos are the best I've found re: the Fiesta ST. (I was going to say they were among the better ones, but now that I've watched several of yours, I think they're the best out there.)
Sure thing! If you have any ideas for other videos or reviews you'd like me to make let me know.
POUND-For-POUND, the FiST is as good as any other car on the road, or better in many cases.
Great review. Enjoy the insight. Am wanting go go hybrid as well for basically all of the reasons you confirmed with your experiences here.
Bought mine last month and i love it! 2014 molten orange with recaro package included. The car reminds of my old suzuki swift gti.
thanks for posting this. i just got a 17 FiST and am trying to take a realistic approach at modifying this car. i had a 400whp evo x and it was not always enjoyable to drive and constantly had little problems. this car is my favorite combination of fun, handling, practicality and being inexpensive to drive, buy and modify. i can see myself doing a setup like yours in the future maybe after the warranty is gone. i do need it to be reliable for awhile though as i still enjoy using it for Uber/Lyft
Varg Sutton Glad to hear man sounds like you and I think the same way. Enjoy your car!
Like your honesty and what you say about the power is just right. 👌
Great videos. I’ve watched all of your videos and I think you u convinced me to trade in my 228i and get a fiesta. Now I just have to decide how soon do I want to mod and void the warranty 🤷♂️
I got the Fiesta for Autocross purposes. Man, what a machine.
Nice series I’ve found that we have just about the same idea about the car. As far as a daily driver with the most “fun factor” for the price you absolutely can’t beat it! 300/300 is where it’s at with 30+ mpg
Good to hear. Good luck!!
Or full traction 350bhp with a proper LSD.... and 40mpg average ;)
Definitely possible with the right mods, tires, etc....just not the money I want to spend on this car. Law of diminishing returns IMHO.
I would love to see more recent videos with this car like maintenance, driving and more in-depth about how driving with this turbo is like I'm about to get the same turbo so I'm being selfish here but would love to see more from you bud
Hmmm I think I've covered it all in my 15 or 20 videos...really no maintenance, just change the oil/filter and empty the catch can at the same time, clean the air filter, keep the tires at the right pressure, that's about it, I've had zero problems. Check out my videos on traction control and race gas/93 tune for driving impressions. If you want more email me at puddleglum72@gmail.com and we'll set up a time to talk on the phone maybe I can answer any specific questions you might have!!
gray25xt thank you so much I appreciate it I will forsure!
Jeff, Another great video! This is a fitting conclusion to your FiST series. I am going to miss them...Maybe an LSD in a year???
Ha ha just can't justify the cost vs. improvement for my style driving but thanks for the suggestion.
Id rather have a stock turbo FiST with a Wavetrac then a stock diff FiST with a bigger than stock turbo but to each their own I guess... Unless you like to spin your wheels all the time from a stop.
I do want a 2014+ Golf R and APR or Cobb tune it (around the same numbers and I know cobb is cheaper stage 3 OTS)... but as you pointed out that car is more than double the cost of a new FiST. The FiST is far more 'raw' a hot hatch also by nearly everyones comparison if you are looking for the ultimate drivers car.
I’ve enjoyed watching the evolution of your car for the last year. I just recently traded mine in for the rs about 2 weeks ago. Hopefully it will be as reliable as the fiesta has been. It was hard to chose between rs and golf r but I’ve owned a golf r before and the rs has more character driving around like the fiesta did.
Thanks man. I wish I'd started the videos back 3 years ago when it was stock but I didn't really start posting much till I did the turbo upgrade.
You are I are probably similar in our taste in cars, the Golf R was a close contender for me. I drove one before buying the Fiesta ST and it's such a nice car, power is nice and it's very luxurious, but it just didn't have the character of the ST. That being said, just a few thousand dollars of off the shelf APR mods and the R becomes a supercar.
Hope you enjoy your RS, they are quite nice as well!!!! I agree on your assessment, the R is nice but the RS has the attitude.
gray25xt my golf r was modified with around and would take about anything. It’s was side by side with 2018 mustang til about 120. It handles great with coilovers but even then there was 0 feedback. The fiesta changed my definition of what every sports car should be able to feel like and be like regardless of price. Looking forward to the next few years to see who will do what next. I’m disappointed with fords decision to stop with most cars but I like almost all car brands. I think ford would have kept pushing the competition to make better and better cars. Hopefully they still will.
Yeah, Ford, meh. It sucks and I agree, but you and I both got some of the last of the good stuff they're offering in the USA.
Your assessment of the Golf R is exactly how I feel...my STi'd Forester XT a few years back was faster and AWD was great but it just wasn't as fun as my Fiesta ST. The Golf R had the same feeling....super fast and really nice but specifically in steering input and road feel it just didn't feel very fun or communicative. Your review there makes me glad I chose the ST because sometimes I wonder about life in a Golf R....I have a soft spot in my heart for them for some reason but obviously I chose the ST and I'm happy with it.
gray25xt yea it was hard not to go back to golf r...I almost did just for the speed but the rs was fun to drive around the block just like the st. I decided I go with rs and wait and see what the next golf r is like. I’m hoping with the rs gone vw will try to blow everyone’s mind with next golf r.
I haven't driven an RS yet but from what everyone describes it's sort of a cross between the Golf R and Fiesta ST. Maybe get some of the benefits/characteristics of both.
X47 is a good place to go defo interesting video. Worth mentioning pushing more whp with a bigger turbo is just worthless as you say not only does it spin way too often it gets very laggy aswell especially in the first couple gear changes
Well not totally worthless, the power is useable in all gears you just can't use all of it in 1st and 2nd, but you still get to use a lot of it in 1st and 2nd.
Great video as always sir. I'd like to see more driving videos personally 😉
Also, add me on Facebook - Lewis Rowe 😊
Hey what's up Frosty. Yeah I don't have jazzy cameras I do everything from my phone and to be honest there's not much else for me to show while driving the car, I suppose I could do some outside footage but meh.
Hope you're well bro. I'm not on Facebook, part of the revolution.
@@gray25xt Good to hear from you mate. You could always set up a phone mount and take us on a fun drive 😉
What's the best way of contacting you personally mate?
Yeah maybe I'll get a phone mount that's not a bad idea. Just busy not much into youtubing I just post these vids for fun now and then.
Shoot me email at puddleglum72 at gmail dot com and we could skype or something if you like and swap car stories.
love your videos! i hope to do a x47 turbo mod sometime in the future after my warranty expires. where did you purchase your x47 turbo?
Thanks Paul. I got mine barely used from a guy I met on the feistastforum.com, you could look there for used stuff that pops up on occasion or pwnall performance sells them stateside, though all they sell now is the X47R.
My personal opinion is that the X47 is a better turbo than the X47R. X47 is the best turbo at the torque/power game under 300whp goal. If there is any desire for about 50whp more VT330 is the best. If maximum reliability for the turbo or power is wanted out of the stock block then 2860R gen 2 or G25 for up to around 380whp on the stock block. 400whp is where there begins risk to the rods and the block has been proven to north of 450whp before the ring lands have issues. Incredible engine in these cars, really.
You st is looks fresh af! One thing though. Dont machine wash and look up how to wash a car if you wash your own car. Youll appreciate it in the long run.
I machine wash my car weekly to make sure nothing accumulated on the body.touchless is key! No scratch baths
i'll share my experience with my 2015 ST. i just passed 105k miles this morning. First trans made gear whine (since day one) noises that got worse, changed at 74k. next one lasted 20k (bought used). this third one has the seemingly known gear whine in 5th and 6th.DESPITE that one issue...er...and the blend door lol... i love this car. at 42k the x37 was put on (yeah its been on AWHILE) with a mountune catted downpipe, GFB DV+, 14psi WG and dyno tuned. I'll mention the CPE exhaust though it's been determined it didn't add any power, made 239/259 which didn't make sense. after switching tuners and ethanol blend the car felt stronger. at 90k i FINALLY put it on the rollers and it made 286/290. feel pretty quick to me BUT..im getting that itch for more power. im not sure whether to go 2860 or mountune MRX. i'm not one of the guys that will add aux fuel though soo im not sure which turbo to get next!
Sweet build! Would you know what the 0-60 on the car is or should roughly be around?
Thanks. With the right driver, traction control on, and a clutch dump I think it would do 5.0-5.5. I can slowly pull away from a 2018 STi if that helps for comparison.
Again, thank you for your assessments and reports. You have an almost, empirical approach to your build that gives great credibility and rational results. At this point, I was wondering if you would ever consider a LSD and if you had ever tried one. It seems that the European 2018 has this. As far as traction goes, this would be shy of AWD but perhaps the optimum this car could be.
Sure thing Jim. Yeah I'm not out to get subscribers or views just trying to help out folks if possible. I'm making the kind of videos that provide the sort of info that would have helped me when I was doing the research and installs.
I considered LSD but I've ridden in a Fiesta ST with 300+hp with LSD and it doesn't help straight line traction much, it's more for holding power coming out of corners. Since I don't drive the car super aggressively it's just not something I can justify adding to the car since it's not cheap.
I respect that you have your own opinion and I wanted to provide some counter discussion on some of the things you have said based on actual experience. I do not have a place to work on the car to this level anymore at the moment but I did the parts install myself that I will be discussing.
Too bad you didn't get a chance to sit in a car with a Wavetrac LSD and a Garrett turbo. This is closer to the style of LSD that rally cars use (clutch pack diff) but doesn't use the clutch packs, which eventually wear out.. it uses a 'wave gear' which is patented tech from Wavetrac. Huge difference in straight line traction. I spent months trying to decide if I wanted more power than stock tuned 27psi kp39 could deliver because of the issue of traction ruining the car, as for me, not being able to use full throttle on a car with under 300whp in 1 and 2 is unacceptable. After much research, and finding a article on a 400whp+ GTi that had no issues driving in SNOW with a Wavetrac differential installed, I finally decided on a differential. Let me preface what I am going to say next with following statement: Not all Limited Slip Differentials are created equal.
Traction and Power:
I can hook 260whp in 1st and 300whp+ in 2nd on 165 width WINTER tires with that diff (tested in summer obviously there would be some slip in winter). Turbo: GTX2860R Gen 2, 280wtq 325whp. I track this car and its been reviewed by a professional driver on track with me who said the power band was perfect and the LSD hold the power down. He dropped it into 2nd on our second pass at relatively low speed and went WOT nearly to redline where power is at its peak and I believe this was my 320whp kill tune, 100% traction no slipping. Its the same story on the street and even in rain and snow the car is better in every situation. Traction control actually helps the diff do its job also along with Cobb traction control.
I still have stock turbo sitting at my folks house and thinking of converting it to a hybrid x47 internals but the extra torque does not seem to help the Fiesta ST driving dynamics in lower gears as higher horsepower does at the end of the RPM band. It is a good hillclimb turbo due to the way the torque can help the car a little more out of hair pins but this is in motorsport format not the street, and with aggressive tires that are heated to operating /racing temps.
From my own experience, I disagree with the statement that more than 300whp is useless on the street, if you have a properly built car. Its not like you need to jump to a Golf R to have more, its still practical and cost effective. I would go as far as to say that if you want more than 250whp, that it is really more practical and cost effective if you put a Wavetrac in the car... unless you wanted the dynamics of open diff and were tracking it. On the street, more than 300wTQ is useless in a FWD car before 40mph, and more than 250whp spins in the lower gears no matter what tires you run unless you have a Wavetrac or a Welded FWD diff in the car. If you do a proper build and do the transmission before the power increase with the RIGHT diff you will find that it makes a massive difference in the straight line AND cornering performance. The Wavetrac is slightly more expensive than the other LSD options out there but its got that key straight line advantage vs those other options.
Sources: I have a Fiesta ST. It makes 325whp 280wtq. GTX2860R Gen 2. Wavetrac LSD.
Good stuff thanks for sharing. What I said about more than 300whp being useless on the street must be paired with my other statement about the law of diminishing returns. Sure with enough mods and LSD and tires and etc. you can get the traction to keep the HP on the road but the COST of that is what I'm saying "no" to......by the time I'm spending the money needed to get more power and have it useable, I'm in RS or Golf R territory and my point is that I'm not spending that much on a Fiesta. If I wanted to spend that money I'd have bought a different car.
gray25xt not even close. Total mods on a 17k new (what new FiST can be bought these days) + lsd + install labor = 20k. Less if you DIY, 18k. Turbo with bare minimum to make it work incl. FMIC 2.5k. So... current out the door pricing on FiST+big turbo+lsd = under 21k still half the price of a new golf r which retails for 40k... or if you wanna look at 2015 prices when I bought my car, 25k out the door+6k MAX in minimum mods+install labor for the mods I’m talking about to the tune of total 31k MAX paying someone else to do all the work for you. And most people are going to install most of it themselves let’s be honest unless you are made of money, afraid of getting dirty, or both. So realistically it’s more like 28k to get it all in the car and working. 12k less then MSRP of a Golf R and still 8k less then RS which is now around actual MSRP out the door as we know they were initially way over sticker
I’d hardly consider within 8-12k of a more expensive car to be in the pricing territory. That’s the price of a used Fiesta ST in that price gap lol
Meh, when you talk about being "afraid of getting dirty", not just any average garage mechanic like myself can install an LSD, that's unrealistic. I installed all my mods in the garage with help here and there but an LSD I am not qualified to do nor is the average person who enjoys wrenching.
I looked at a brand new Golf R back in 2015 that was 26k out the door after incentives...add about 5k for an APR stage 3 setup and you're at nearly 500hp, a 10 second 1/4 mile and 0-60 in 3.4, all for $31k. So yeah your 31k for a big power Fiesta is not such a deal.
Thanks for your input though!!! In any case my point here is that I'm not interested in doing more to my car; the way I have it setup right now is perfect for me, I don't need LSD, my tune takes care of traction issues....the power is right....the balance is really nice. To each his own!
I gotta get mudflaps for my ST, what am I doing?
The car has been reliable and that’s good to hear! But how often to you push it hard? Thinking of going x47, but not sure if will hold some daily redline!! Thanks if you reply, sweet ST btw👍👍
Thanks. I redline every time I drive, so daily. But I'm not into autoX or dragstrip, more of a daily driver. I think both the ST motor and the X47 are pretty sturdy.
I second that. This engine is incredibly strong for a 1.6. It will put up with about 100whp per cylinder, or about 250whp per liter before it needs internal upgrades. I push 29psi / 300whp on the stock block and redline the car daily nearly launch it daily and do track days. Also, stock clutch takes it, cvs start to complain with launches after a while but the motor just keeps plugging along no piston slap, no rod knock, no significant wear noted in oil during changes. The 1.6 clock just keeps ticking. If running ethanol I would recommend upping the oil change interval. 3000 miles minimum 93 (E10), 1500 miles interval recommended e85. Roughly every 2000-2500 for e30 or other gasoline blends cut with e85.
Id be happy to keep my ST forever too. I have to make the decision keep and X47, 330r etc or get the new ST, Im leaning towards upgrading.
The real question is How hard were those 10,000 miles....? Definitely interested in a BT for my FiST!!
Not sure what you're asking. One measurement I use is the condition of the motor mounts. Yes I redline every time I drive but I don't beat the car or rag it all the time. I recently installed motor mount inserts, and my stock mounts were in perfect shape which tells you something. Many folks are blowing the stock mounts out by driving aggressively, but mine were fine. Also some folks are blowing the inserts out as well by aggressive driving, mine are fine. So on the spectrum of car abuse even with me hammering it frequently I don't think the last 10,000 miles have been too hard on the car, judging from the condition of my mounts and my MPG.
How difficult is the process of installing the x47 vs. the other “big” turbos (mountune MR265, etc)? I would like to be around 270-300 whp. I’m currently stage 1 with a custom tune from mountune for reference. Thanks for your updates and input with your build.
James Rock Hybrid turbos aren’t that difficult, but some of the other big turbo options are a bit more involved with a V band clamp and other differences. Look up T-shirt driving channel, he has some good detailed install videos for our cars.
gray25xt also, I couldn’t help but notice your profile pic. I was curious if you’ve baby’d with ST. Got my first on the way and I’d hate to get rid of the car.
Yeah a kid is no problem, in fact I have 4 kids, they will fit in the back just fine until about age 10-12, that's when their knees start pushing against the front seats from behind. But the Fiesta isn't a family hauler by any means, and getting a kid in that tiny backseat into a carseat would not be fun with all the bending over and what not, there isn't much room. So it will work but the first time you put the kid in an Accord or larger car you'd immediately realize how much easier it is.
Hey man, 2 quick questions. Are able to run the stock clutch at those numbers? Do u know if you can run the Boomba bov on the x47? Thanks!
Yes stock clutch is good till around 375whp. I'm pretty sure the Boomba bov will work but I'd ask them before buying.
@@gray25xt thanks!
Quick question I assume you had a tune ready before you started your car right? I'm getting mine installed soon and idk if I should have the etune before I start my car? I'll be using Tune+
When you order the tune he'll send you a base tune, you load the base tune up once the install is done and start logging, then send the logs back to the tuner, he sends a fresh tune, repeat the process, usually after a number of revisions you'll have the "final" tune.
@@gray25xt thanks man you've always answered my questions I appreciate it
@@ImFAULKn Happy to help.
Hey gray what about the brakes a lot of people are running a big brake kit when surpassing the 300 HP
I'm on stock brakes. In fact I'm still on my original brake pads at 37,000 miles now. The reason people upgrade the brakes is because of the whole "if you accelerate fast you have to be able to decelerate fast" mentality. However I think that's dumb. On the street you shouldn't be in a situation where you are ripping the car and then need to stop faster than normal. If you are you're likely driving in a way that is unsafe and illegal. Also people just bandwagon because they need something to spend their money on and go with the crowd. Hope that helps.
Please let me know when you’re ready for your next project. I’d be VERY interested in purchasing your Fiesta ST.
Wow what a compliment thanks Bob. Where are you located out of curiousity?
gray25xt Bloomfield Hills, Michigan - about 20 miles NW of a Detroit. I’m actively looking. B2@robertbiess.com if you’d like to talk further.

Cool. Unless something unforeseen happens in my life I plan on keeping this car for a good many years to come but I'll keep it in mind. The thing is I've got more in the car than I could even sell it for so it's a losing proposition for me...$25k spent plus my labor, even with the mods it's only worth maybe $20k...depreciation mods are not a return investment....but even so I love the car and don't want to sell it anytime soon.
In the meantime good luck finding a car, there are some great deals on both used and new Fiesta STs right now, I've heard of them brand new (stripped) for $17k and seen used ones with decent mileage for $13k. You could get my entire setup for under $20k on a used one if you weren't paying for the labor.
While I understand your decision to not do an LSD... but at this point I would say the torque these make would make an LSD a serious upgrade and make it more feasible in multiple environments beyond just straight line speed. I'm considering doing it BEFORE I look at the turbo.
LSD would be nice but the cost doesn't justify the gains for my driving style/needs. Do I want one wheel spinning or two? I'll save $1800 and skip this mod. Would be nice to have. You have to stop modding somewhere though. Been down that road with previous cars, learned my lesson.
Odd question, I have just done a Turbo Swap. How do i crank the car without it starting? To Build up oil pressure.
Hmmmm....I don't want to lead you astray and have you damage the car so I'm going to recommend you search and find what's best for you. There are multiple ways to do this!!!
4:40 car sounds great 😂
Are you on Ft Benning? I swear I saw this car there the other day.
Hope, Augusta GA.
@@gray25xt I am pretty sure I saw one just like it on Ft Benning GA the other day. He must have been watching your videos.
How do you find the stock clutch is with the turbo upgrade? I'm assuming you haven't upgraded that already.
Bryan Twigg stock clutch is aftermarket. Supposedly good for 380 hp.
Yep like Agent K said clutch is fine no issues until you approach 400hp which will not happen for me.
Good to know, I've had a variety of relatively quick cars before. The Fiesta ST is slow stock or even at stage 3. I wouldn't mind if it were as quick as my Cobalt SS/TC (which I left stock,), feels like it would need a turbo upgrade to get there.
Bryan Twigg all you really need that matters most for power is cobb stage 1 with drop in filter and upgrade intercooler and get a protune. If you’re still not happy get x47 with a downpipe with tune for e30. You can do full exhaust and intake but it won’t help a much powerwise to justify the price. Going beyond that is just way too expensive but if you want more than 300whp you’re looking at $2500 just for a wide body kit with wider wheels and tires. For that price you can do all the stuff I already mentioned. It wasn’t made or geared to be a drag racer but with that power there’s not much that can keep up with it on a backroad or a track. With 300hp and a lsd it is by far the most fun car to drive for the price.
@@agentk4257 true, I've done stage 1 stuff and it's a blast to drive. I'm adding upgrades periodically just because it keeps me happy. Just did the full powerflex motor mount inserts per Jeff's previous vids ... Love that mod! Intercooler as you said could be my next "big" mod.
I like your videos alot but i disagree on some stuff u said about the 👊. I think the car has plenty of power and torque from factory stock. It won't be a 5.0 or v6 accord in its stock form but it can keep up or pass alot of other cars on the road. Ill get a cusom tune and a ap and a bigger intercooler. 215-220 hp and 280-290 torque is plenty quick in a st for me. It has a great weight to power ratio. Just my humble opinion. Good luck with your fist.!
Yes you are correct it's quick just not fast. Depends on your needs. When I say "its not fast" I'm saying it's not in the league of sports cars. I'm coming from a faster car (STi with turbo upgrade) so to me the ST in stock turbo form is slow.
In its class its the fastest car out there though... If we compare apples to oranges there is always a faster car. Subcompact hot hatches there are not many. IIRC actual in class (subcompact) competition is... Hyundai Veloster Turbo(?), Fiat 500 Abarth, Chevy Sonic Turbo.... what else is there? Mini Cooper S? I've probably put some compact cars which would be the class above the FiST. It tends to already punch above its class to begin with. Comparing the car to a WRX or STi is an apples to oranges comparison as those cars are classed higher. In Forza you'd have a 'C' class for the Fiesta ST and a 'B' class for the WRX and an 'A' for the STi probably lol
Well said Andy.
Agreed, although a tuned F56 cooper s with just intercooler and downpipe upgrades and a tune are hitting 310...pretty mad
Can you please tell me your wheel set up? Rims size and tire size etc..
Rims are 17 x 8 with 40 offset. Tires are 215/40/17 which is +1 size. Check out my review of the ROTA GRIDS for more info on the rims and FEDERAL TIRES for more info on the tires. I have a video on my channel for both.
The one weakness of the car is traction.
Rather have the cobb turbo upgrade you get power everywhere not just on mid rpm and top end only
There is no Cobb turbo upgrade available. You need to do further research.
The only place this car needs more power is at mid and high rpm, there is already far too much power at the low end, even from the factory the tune is significantly limited to that the tires don't roast, and power upgrades only exacerbate that issue.
Are you getting that power on 93 octane pump gas?
About 280 on 93, the 300 is with Race Gas concentrate, see my other vid on that.
How bad is the hybrid whine?
With my CP-E intake it was atrocious, however since I swapped back to stock airbox it's barely noticeable.
I kinda skipped through the video but are you running aux fuel or meth?
Neither just 93 tune and 93+race gas concentrate tune (99.5 octane).
I'm getting 260whp on my x47r. I'm quite sad lol
What kind of fuel? I made 304/337 on race gas concentrate and 277/322 on 93 pump gas. If you are on 91 octane 260 is about right. If you want more power you might get an ethanol tune or try some race gas concentrate and get a tune, see my video on that for more info...
I'm on 93 Sunoco gas. Luckily, I have an e30 station nearby and Adam can get me a tune for it. 277 is what I'd like to get on 93. You sir are very lucky. Maybe the ported manifold does help a lot.
@@gray25xt
@@markbatarina4512 Hmmm...260 whp what was your torque number? The ported manifold might help a bit, it could also be that I had higher octane because of the race gas concentrate still in the tank even though I was on the 93 tune. Also if we were on different types of dynos that could make the difference. I've got a few other goodies that might have helped too like my big mouth intake snorkel. And depending on where you're at, humidity and temperature all that stuff makes a difference. Still you aren't far off from my numbers.
Stock fuel system?
Yes. 93 octane is 275-280hp, add ethanol or WMI or RG concentrate to get near to 300. Aux fuel will take you higher maybe 315-320 but it hurts mpg more and again back to my thesis of this video, over 300 hp the car gets unbalanced imho.
It actually doesnt hurt mpg more. The split second controller is hooked to a hobbs switch and only turns on around 24psi of boost to supplement the Direct Injection. If you are hyper mileing for MPG you are not building more than 5 psi of boost if any boost at all so you will not even use the aux fuel or meth injection system as they all use boost switches set to turn on at high boost where the factory system would have begun to lean out...
No differential?
Negative.
@@gray25xt well, I'm told it's night and day even on a stock setup. The quaif lsd that is. Can't speak for other brands.
@@khayrobs It is on the track. On the street, not so much. Just means two tires are shredding instead of one. If I tracked the car LSD would be a no brainer, but it's my daily driver so it's not necessary nor worth it for the price.
Well, I'm not gonna track mine but the guys with the big hp on these say it's worth it on the street 100%
I'll find out soon enough. Gonna be my first upgrade once the warranty expires.
