Great video guys! I love my 5star tune!
Thanks
Godzilla not gutzilla
Wondering if it’s compatible with the cab chassis Ecu?
Will the 5 star tune void your warranty, or affect mileage much?
Watching all of the TFL videos I went out and bought the 7.3 with 4.30 gears. I so wanted a Gm but the ike test changed my mind 3 minutes faster is mind blowing. Truck manufacturers should be aware of the influence you have on potential buyers. Mine is a F350 and pulls my 13000 lbs toy hauler through the foot hills of Southern Alberta with ease, better then my 05 5.9 Cummins and the same fuel efficiency.
Great to hear, i prefer gm gas trucks myself, they seem the best value used to me and easier to work on than fords in the engine bay, some of the gas v8 ford trucks are not fun, for example if an exhaust manifold goes out. I prefer the ifs and they are much easier and faster to do alignments on, in the salty NE anyway. But gm is definately behind power and transmissionwise compared to ford and ram. Like toyota tundra, probably played it safe with old design for too long. Its not like they needed to design a whole new engine, theyve had the 7.0 ls7 since the mid 2000s. I dont understand them only using a 6.6 gas direct injection only to replace 6.0. They easily could have made it 7.0 or more, and still only has 6spd, granted its solid. The direct injection only will likely cause carbon buildup without regular cleaning. Be interesting to see how they compare as they age. Im sure gm has more working room underhood, but then has the direct injection to deal with.
I w been telling everyone this. The 7.3 Godzilla pulls better than my stock 2002 7.3 power stroke. And damn near toe to toe with a my other modified 2002 7.3 which has bigger injectors, bigger turbo and intercooler. I’ve discovered the biggest differences to be as followed..
Overall, the 7.3 gas is my go to over my stock 7.3 powerstroke up to 15,000#’s. When I’m hauling a good neck and hay that’s close to 20,000#’s I’ll opt for my modified 7.3 powerstroke. However, the exception is when the modified 7.3 diesel is actually up and running. A modified 7.3 powerstroke is just open to more wrror codes and limp modes due to all the upgrading. So when my modified diesel is down, the 7.3 gas is still up to the challenge of 20,000# loads, it just gets crappy mileage and have to drive 50-55 and can only maintain 50 up steep grades.
Overall my everyday driver and preferred tow option is the 7.3 gas
Same here! I almost pulled the trigger on a 2500 Chevy gas until I started reading about the direct injection problems then seen the Ike Gauntlet comparison. After doing a lot of research, Ford switched this lifelong Chevy owner and I never looked back. I love my 7.3 F250!
Also interested here in Kelowna. What toy hauler?
@@davidc1961utube a 2006 Fleetwood gear box model 335fs. It is built like a tank!!
Keep pounding that Ike with big trailers. It never gets old Guys.
Way to go outside the box fellas, the best video I’ve seen from you guys and I’ve been a subscriber for almost 3 years. Thank you team TFL
I have a 7.3 Tremor and pull 9000 pounds. Tell Mr Truck to use the Cruise Control. It shifts way faster and holds the speed perfect. Non- Criuse there seems to be a delay between pedal and throttle response.
I have noticed that when I use cruise control it does not monitor the RPMs correctly. For example. If I'm going up a slide incline on the interstate and I slow down just a little bit it will drop it from 10th gear down to 5th or 6th Gear and over rev the engine. I do think they should pay attention to that and change the where your downshift so far. I have a 2020 F-350 Lariat with a 7.3
I’m loving my 7.3 with the 5 star tune so far. Had them tune my 2013 f150 5.0 and it ran great the whole time. Tow tune is great on highway. Around tow I leave it off though. Keeps me in 3rd/4th around town with a 7k landscape trailer. No need for it at 30-35mph. Truck pulls in default mode like the trailer isn’t there and kicks to higher gears saving me gas. 87 daily/tow is what I run 90% of the time. The 87 performance tune was really snappy as well. Love the throttle response vs the stock dead pedal. Zero complaints on this truck or tune after 4K miles now. We shall see how the 10 speed does plowing this winter though.
Do you have a 4.30 gear or 3.55?
@@granttyler1254 3.55 gears
Have you had to get any warranty work done? I’m wanting to tune my truck but I’m afraid of voiding the powertrain warranty. If you switch it back to stock can the dealership tell?
Would love to see this same comparison but on your 80mile loop. See what kind of fuel savings tuned vs stock would be
@@boobacockaa lol I was going to say the same thing, it's no diesel.
There entire reason there is power left on the table is because it's tuned for peak BSFC from the factory (pretty much stoich). Not gonna be much left on the table.
@@corystansbury Mine isn't tuned , but I installed a pedal commander and it's like night and day.
@@rustynail7866 That I can believe. They hold these things back quite a bit even relative to what they're tuned for.
Andre and Mr. Truck. What a good combo and an awesome test. Good job guys!
Thanks
always great to see you two together again!
Thanks
It’s amazing how better towing has gotten. At work, the truck I drive has a 5.4 triton, I tow a water tank that holds 3 tons of water, 5.4 has no balls to begin with and then towing with it makes it so much worse. I am a Chevy guy through and through but seeing this new v8 from ford makes me happy, cause it proves to me there not just working on the powerstroke or the turbo charged v6s.
Great early morning drop. Love Andre with MT. Good paring for these tests. Thanks for not using “beefy”. ✌️. I have tuned vehicles. The factory tune is done by engineers who know what they are doing. They tailor the tune to fit the market for the vehicle. They don’t “leave HP out” because they are dumb. They do it for a variety of reasons including longevity. They work with a wide variety of manufacturing tolerances and driving habits and have reliability goals for the fleet. They tend to be conservative
Thanks
Amazing with 37's ran up like a champ no sweat!!
Ike gauntlet intro music never gets old
Great video like always... keep it up guys
That new 7.3 was at my job a month ago! Beautiful overland set up!
That 7.3 gasser is impressive, loaded with that camper, pulling a trailer with 37s I'm impressed
Great video and good dyno results for a naturally aspirated engine.
Sweet, let's get the supercharger on it and try this test again.
Big Injun That would definitely put the cooling capabilities to the test. Supercharged engines run hotter.
@@EricFortuneJr. my mustang ran a lot hotter when the coolant loop that ford installed kinked. Couple blown head gaskets later and ford got the opportunity to practice taking heads off free of charge.
Can confirm, supercharged tacoma is way more fun and tows better.
Peeon the3rdrail I need to supercharge my taco 🤙🏽
@@freedomisntfree_44 dude, do it. It's great. Just make sure you upgrade the clutch if you have a stick shift or put in a shift kit if it's an automatic
Having a 5 star tuned F150, I know that there is an immediate change in both the engine and transmission. But from experience, there is a decent change after putting several hundred miles on the truck after the tune is installed. I noticed that in tow haul mode, the transmission is much more aggressive with downshifts and slowing down a truck and trailer then when first installed. Truck is a 2018 F150 2.7L Ecoboost.
Kevin, I have the same tuck as you, did you see any change in mpg? thanks
@@patcarden3028 to be honest I really haven't gotten any difference. I don't exactly baby the truck but just cruising to work I'll get about 21 or so, though on a trip down to virgin I averaged 24.5 on the tow preformance tune
@@cummings2101 Thanks, I need to look into the tune, I have 4x4, 3.55 gear, and I get 19.5 in town, and on the highway, it drops to 18 or so going 75 to 78 mph, thanks for your help, take care.
Great job guys - 5 STAR seems the way to go 🍻
Love that 89' !!
Good to see Mr Truck!
Do the same test you did with the F150s. Quater mile towing stock vs quarter mile towing with 5 star tune. Would be great to see the difference when flat out!
3:45 along I77 near Fancy Gap VA, I've seen a number of big rig runaways in the gravel runoffs. Others pulled over on the shoulder with brake fires. Heavy hauling in the mountains is no joke.
I-70 has seen huge numbers of accidents because people do not understand what steep mountains do to vehicles maxed out.
I drive that 2 times a month it's a serious section of road
Fancy Gap ain’t no joke in a Semi truck, been up & down it in every conditions 😬
I see that up here in the mountains through Virginia and North Carolina too; I’ve towed through them and it’s definitely no joke, and the mountains out here are no where near as high as the ones in Colorado
Just pulled my camper through fancy gap. I live in huntington wv
I just watched some random video compilation yesterday that had a clip of a tanker truck taking that exact same runaway ramp. Crazy
You guys, should do a quickie, on the newly imported, 2021 Honda Trail 125,, (CT125). Yes, It's basically the trail 90/110, we all know and love!! The bike fastened on the rear of motorhomes everywhere, from the 1960s-1980s!!! Now with fuel injection, led lghting, on off tires, electric and kick starting, and digital instrumentation!!! So much fun!! 4speed with automatic centrifugal clutch!!!😁
I have the same truck with a Carli 3" level set up and 37's. I also have the 5 star tune... Question: did you use the 87 octane heavy tow tune application when doing this test. Love this truck and I switched from a Powerstroke and pleased that I did. I don't tow every day and the over all savings is excellent.
Mornin TfL .. 😍
Gr8 vid. 2.8mpg's dudeee that's crazy!!
Very happy with my F250 and 5star tune! Coming from a Diesel and very happy with the 7.3 V8 in stock form and especially after being tuned!
What kind of mileage you getting with the tune now?
@@justinmiller33 driving hwy @75mph average is 15-16mpg, if you drive 65 it will be more in the 17-18mpg range. Very hapy with it, this is with 35's.
Thinkingnof trading my 19 powerstroke for a 20 7.3 with 4.30 s
@@WinningDeadlyEncounters thousands of people are in the same boat, or were and they are making the switch. Its allover. The main downfall would be pushing 30k everyday with heavy equipment or carhauling 3-4, at that point you should be using a semi anyway.
If any one is curios the 7.3 with 4:30s and 35s revs 1900 rpm at 70 miles an hour
LOVE these tune tests! Can we see a ranger tuned for the test!?!?
awesome video! Im still curious how the ford V10's would perform on the Ike
I took my 02 v10 up the Ike when it was new. 6000 lb travel trailer quad in the bed. Had exhaust cold air 3.73 gears and Diablo chip. It was very humbling.... I could only hold 40 mph near the top redlined in 1st gear. If it shifted into second it would just slow down. The following year I had a powerstroke same load 1/2 throttle 75 mph laughing my ass off.
@@dana.6695 Hahaha, just imagined passing you and watching you laughing
@@dana.6695 with 4:30 gears you would have held 60 . Big difference.
I would love to see this tuned vs stock vid on a f150 powerstroke!
Gents, awesome videos covering all aspects of these Ford rigs! Just a little consideration here: why advertise the time to haul (over a given distance at a given speed)? If you tow at the same speed, the time will always be the same over the same distance.....not sure why you make an issue of that. But I love your videos!!! super awesome, just elaborate on the value of this analysis, thanks!
Setting a baseline to compare other trucks with characteristics such as mpg, breaking, ride, throttle response, transmission, and such I would guess. Some brands may not hold speed.
I'm paying a lot of attention to the 7.3L towing.. this is where i"m looking to get into an F350 4x4 Crew with max tow, fifth wheel, and gooseneck packages, and 3:73 gears.. friend has one set up like that that's got a 4474# payload and 15k towing cap. He's towing a travel trailer and getting around 15mpg highway untuned.. I'm looking at going to a fifth wheel (14kGVWR).. so hopefully this will be a good option since I don't want a diesel.. blech. Thanks for the video's, I'm looking forward to seeing how this truck keeps performing!
If you want max towing, you’re gonna need 17 inch tires, the 4.30 gears and that also raises your gcwr to 27,500. You’ll be able to pull 19k pounds fifth wheel / 20k goose neck.
Do you guys plan on tuning most of your project trucks? Would love to see the crazy numbers you guys can come up with
Wanted to support you guys by buying a few T-shirts. Was disappointed to find out you don’t ship to Australia.
Looks like they have plenty of money. They play all day and have shops do upgrades and additions. Drive it in and pay other to make your truck look great. Sounds too sweet.
13:38 - looks like the transmission is starting to get a bit warm.
[edit] - just got to the tuned pull section - you guys called it out at that point. Thank you for being transparent about how these trucks run! Keep up the good work!
Yes.. trans does get too hot...need a good cooler with a fan✌
Awesome truck 👍
Best truck channel out there.
Automatic 'Thumbs Up' for expanding your towing tests of the Superduty to include towing something less than the MAX. Towing 10k is a GREAT choice, as that is closer to what most owners tend to tow.
great video.ok you all talk me into getting a f250
Damn guys, 239 on the transmission? That thing is cooking!
You would think that, but the new transmissions run hot! A stock 10 speed runs at 195 minimum, and 40 degrees of increase is not bad.
You can get a lower thermostat and more aggressive fan curve to help, and that is what I do. Mine has never been over 210 now with a 170 stat and aggressive fans.
Sweet. I'm considering trading my 2014 F250 with the diesel 6.7 for a new F250 with the 7.3 gas. I'm tired of the diesel repair and maintenance costs. I only tow a 9,700lb 5th wheel and it appears a stock 7.3 will handle it well. It is kind of strange that Ford named the 7.3 Godzilla and the 6.7 Scorpion. The 6.7 is a freaking BEAST, but I no longer need that power and costs that go with it. Thanks for the video.
Yeah that 7.3 should do good. Just pulled my camper thats 8k through mountains of Va with 6.2 gas f250 and it did great. Ran 60- 65 mph max rpm was about 3800
Well.. like the 7.3 gasser it wasn't dramatic. But great video!
Be nice to know how much the Star 5 upgrades were and a link to 5 Star tuning
On 37's on a gasser one cannot complain at all with the over all performance I don't think 👍👍
I really enjoy having a brand ew truck getting tuned.
Us average cats need to wait til our warranty is up!
If we ever let that happen 🤪
Mr trucks hands were moving a good bit but between wind and a lift kit, looks very safe.
My warranty ran out on my eco diesel and I deleted it first thing. Wish I would have done it from new...
I would really like to see the Ike test with a supercharged 7.3L
Really? How does anyone give thumbs down to videos like this? If we had the ability to freely share knowledge globablly in this way 35 years ago, would there be as many trolls? Did the internet cause it or were they always there and just being quiet?
That intro music, Thought I was watching Off The Ranch Channel!!
They've been using this intro at least a year before off the ranch.
@@JohnDoe-nz6bk OK. Not say the stole it lol. just a observation
Chris Barr lol, OK.
Yup, definitely recognized the theme. Threw me off for a bit.
I love this truck, just can't justify the price.
Got my '16 Tundra for $31k. With 15k miles. TRD off road SR5. Tows 10k lbs just fine. 4.30 gears, 400 lb ft, 380 hp. And its a Toyota, great resale and Ford has burned so many loyal customers over the last 20 years with their garbage engines they won't stand behind.
That's a beautiful truck. Now to convince the wife I have to have one. Thanks guys.
Would have liked to see the test in stock suspension form .
I had the Ford F-150 FX4 twin turbo EcoBoost 2013. With the trailer and the tractor and my implements it was just a little bit over 10,000 pounds. Paying attention to my weight distribution everything was really solid and I put probably about 8,000 miles on my trailer with that F-150 setup. It was completely stock except I had aftermarket wheels and tires. Pulled it easily. I'm not joking or exaggerating it was clean and safe. I recently traded that in for 2020 F350 Lariat with the 7.3 L godzilla. There is a noticeable difference in the control of the vehicle, when it comes to the weight of the trucks, but my F-150 had over 420 foot pounds of torque. It was no slouch and when you're talking about miles per gallon so far with 3,000 miles I have roughly the same miles per gallon that I did with my F-150 EcoBoost and my 7.3 godzilla. My certified used F-350 Lariet was $71,000. I only paid $24,000 for the Certified 2013 F150 Fx4 stock. So take that into consideration when you have to pull a trailer daily.
you can adjust your tire size and tpms via forscan. that tune is not the only way...
would love to see a completely stock truck with normal tires and springs do it pulling the same trailer 🤔
Exactly
They have a video of a stock 7.3 doing the Ike Gauntlet, look in the video library you should find it.
I didn't think it would do that well without the tune, in essence with your new tires you took what was a 3.73 diff down to 3.34 (assuming that truck came with 275/70 x 18 tires) so I thought it would take 9 minutes or more to make the climb.
3.55:1 for a F250. 4.30:1 for the win.
I have a 22' 7.3 gas and when putting on cruise control, the trans will automatically downshift to try and maintain desired speed. Not an exhaust brake, but I'd put money I could go down with less than 7 brake applications.
Lol
Damn I love this channel. FX5 is hilarious
So every since I started watching Andre and Mr truck towing things I find myself critiquing the tow set up of everybody I see with a trailer
239°f seems hot for a transmission. My ram only got 175°f pulling 2hr and 30mins at 70mph
the new transmissions run a different fluid and are suppose to run hotter for increased efficiency.
You guys Rock, great review! What's up the the fellow tow man in the Ram swerving and cutting you off like that, geez!! Andre looked like he was mad doggin' his @zz as they passed!! Classic!!
Thanks
Super Ike gauntlet 🔥🔥🔥
At the top of this pass, there's about 36% less oxygen than sea level for a given volume of air.
Reciprocating engines have many internal static losses that are the same regardless elevation, and their HP rating factors these losses in at sea level, but simply subtracting the available air to an engine does not appropriately account for the static losses because the reduced available air is always "applied" to the wrong figure.
A large displacement naturally aspirated 400HP engine actually has to make more like 480HP to have 400HP available at the crank after all reciprocating losses, pumping losses, friction losses, and static load equipment losses are factored in (steering/alternator/AC/etc). Take that 480HP engine and subtract 36% power, then subtract 80HP of static losses. Actual crank HP at the top of this pass is closer to 230HP, or ~43% power loss.
Turbo's can correct for a lot of the air loss, especially turbo systems that a are regulated based on absolute and not relative pressure, but even relative systems will cut losses from air by half or better since a turbo's are "decoupled" from engine RPM and will spin at higher speeds when the supply side air is thinner. Smaller engine size also reduces static losses (less reciprocating, less friction, less pumping loss), so a 400HP turbo engine at the top of this pass may only loose ~18% due to elevation, and then, since it's a much lower displacement engine, may have only needed 450HP before static losses to get there... Result: ~320HP available at the top of the pass instead of 230HP. Only ~20% loss in total instead of ~43%. This is why those ecoboost trucks and diesels work so well on these mountain passes when loaded.
Sae figures account for much of what you’re talking about. Crank horsepower is just that. Net rwd horsepower is just that. I think everyone that watches this channel realizes these simple facts. We also know that n/a motors lose hp above sea level, and that forced induction helps with this some. The losses at 10,000 feet or whatever also depends on temperature, humidity etc. basically, my point is that thanks, but we’re all already aware.
@@AnyManProjects Obviously you're not already aware, because SAE does not set any standard for de-rating at elevation. SAE only accounts for those static losses at the crank at sea level. The 3% per 1000ft "rule of thumb" that everyone uses ONLY accounts for the reduced air and has nothing to do with SAE. In this video they said "about 1/3 power loss up here" and while that's roughly true, it's important to note that a massive NA engine will actually be worse than that. Someone might want to know that at the top of that pass their 400HP engine is barely better than 200HP.
Eric M We’re all aware of these basic facts, jeez man, you must be fun at parties. But what you didn’t specify is that torque isn’t affected the same. It actually fairs better at high elevations than hp does, but whatever. Maybe next you can explain to us dummies why the sky is blue
@@AnyManProjects The sky is blue because light diffracts in the atmosphere. But anyway, I have worked at major manufacturers where turbos were specified to maintain sea level MAP to 8000 feet, then derate was allowed. So on the Ike, such an engine would only lose about 9% power.
Andy Harman LOL-thank you
Would love to see mr.truck do a build on tfl
i think it would be pretty cool to see an old 7.3 powerstroke vs the 7.3 godzilla.
"I'll do without cruise because I want to keep it as close to 60 as possible" Or you could use cruise and take your error out of it....but ok.
You guys need to do a another run so that tuned run would be a clean run like the stock tune. Hard to know how much the the tune really helped since the tune time was not a clean run.
Damn I’ve seen the run away truck ramps used many times there on Eisenhower tunnel monarch pass is any other places I’ve seen used many times over the years
Any plans to regear to 4.56 and add a front locker?
I think Andre has worn that t-shirt 3 weeks straight from sun up to sundown.
Wondering what the differences would be running Hi-Test with a tune? My 5.0l F-150 is a very different beast when towing with Hi-Test.
Always subtract 20 seconds from the time when Mr dump truck is driving LOL
6 or 7 extra seconds faster up the gauntlet for a $600-$700 tune... I'll stay stock...
the reason you never see trucks on the runaway ramp is because if you know how to use your jake brakes, you should never be in a situation that you have a service brake failure, outside of a legitimate mechanical failure.
How many jakes brakes do you have on your truck?
I would like to see this with 4:30 gears and the 37 tires that thing would fly up the Ike maybe outrunning the diesel because of the rpm advantage
You were "within a few seconds of each other" on the two runs, but the stock run was still slower even though it was a CLEAN run without some distracted asshat trying to run you into a semi truck, forcing you to brake during the tuned run.
239° is too hot for my blood. You start seeing transmission fluid degrade at around 230° with the load on this truck making this run it’s understandable, but if I hit 220° I install a bigger transmission cooler. The cooler I run on my Tahoe to pull my boat (about 7000lbs)is pretty close to half the size of my radiator but I have yet to see a temp over 205° and that’s only in the stop and go traffic with a 45 mph speed limit! No shame in a monster transmission cooler!!
"squashy" tires or tires low on pressure are not smaller in circumference. The rotation per a mile is the same. Because you measured it at 36" doesn't mean it covers less distance per mile. Keep it set for the size of the tire regardless of how "squashed" it is
Most 37 inch tires actually measure half inch less. Just look at any manufacturer's website.
That idi is my dream truck and color . Wish I had the money for one
Andre said Ford calls the 7.3 a big block. Got a source? I’ve seen a video with the head of Ford Performance calling it a small block. It seems to be a good engine so far regardless.
But did you run the comparison in the same direction for both test? Eisenhower definitely feels steeper on the west side from my experience
Just curious why yall never use cruise control down Ike? I know the adaptive cruise holds the speed you set even with a 18ft trailer and a large UTV on it. Not sure if normal cruise does but I believe it will.
BIG mistake tuning and putting a camper and 37s on a 3.55 geared truck! The second owner of this truck had transmission problems once TFL sold it to him. What a surprise! Should’ve gone 4.30 gears. It would’ve made a big difference.
I would like to see the same test on a truck with the 4.30 gears.
That 7.3 and 10 speed really work well with 10k on the back.
Yeah, the 4.30 rear helps slow it down a lot
I don't know why they even make the gasser with 3.55 gears! They should all come with either 4.10 or 4.30 gears.
@@charlieodom9107 because the transmissions now have the ratios to make up for it
@@jasonharrison25 incorrect!!!
The 7.3L gas doesn't disappoint.
That OffTheRanch intro song 😤
What sway control setup are you using on the gen y?
Whoopsey. overloaded the payload a decent amount this time. 780lbs over GVWR according to the ticket . Depending on what spring pack you got from Carli, it looks like the load capacity could have been lowered compared to stock as well.
It wasn’t lowered. Carli had Deaver build a custom pack that accounted for the camper in back full time PLUS stock payload.
I know none of that changes the trucks official rating in DOTs eyes, but performance is equal or better than stock.
@@upshifter5316 That's also over 2000 lbs of tongue weight (if that is indeed a 10000lb trailer), which legally counts towards payload directly, but physically the tongue is two feet behind the rear axle giving a lever and fulcrum that greatly reduces steering axle contact pressure. With that much on the tongue it will also have the propensity to plow anytime they brake and sag anytime they accelerate, reducing the front axle weight and adding to the rear even more. That's why it's highly suggested to use a WD hitch on any tongue load over 1,000 lbs on 3/4 and 1 ton SRWs. I believe their gen Y setup has 1,700lb rated bars on it (but they looked awful bendy), so the reality is the trailer is loaded pretty heavy in the front, or the camper is heavier than they think. Stock, the rear axle rating is 6340lbs, they are already exceeding that static, it will be more under acceleration and braking. AND Andre wasn't in the truck when it was weighed, so that's about another 240 lbs on top. Altogether, the truck was overloaded by 1,000 lbs, or the entire average payload of a Toyota Tacoma. Also, if it was a spring lift, and not a block lift, even if they are heavier springs, they are longer. I don't see anything special about them as they are a three pack with an overload, which is exactly what you find on a camper package F-250, or stock on a 350. The only leaf setups I saw from Carli are one that maintains stock capacity, and one that is softer. The F-350 srw has heavier hubs and a bigger yoke on the diff side of the driveshaft compared to the F-250 (It may also have thicker gauge frame rails over the rear axle, there's about 250lbs of difference between them), the spring pack is essentially identical. So no, you don't just put bigger springs on it and make it a 350 either.
MSTRCHIEF143 Agreed.
MSTRCHIEF143 the rule of thumb for a bumper pull is 10% if the weight on the hutch so that’s more like 1000lbs, not 2000.
James Beaman Agreed. But in another video they said gunsmoke makes it impossible to achieve 10%, with all the weight up front in the engine. I think that’s why the squat is exaggerated in all the videos they tow this setup with.
Loading it backwards would be less safe, too much sway.
Solution for squat with the load: the F-350 S D.
I need tunnel runs with that exhaust please🤤😍
I know the Ford and GM's have the same 10-speed, I feel 239 is high. My Yukon 6.2/10speed doesn't get that high. Of course, I'm not towing close to 19k lbs at 7% grade. But I wouldn't feel comfortable at that high IMO.
They might have started at same point, but this 10 speed is quite a bit different from the one in your Yukon, and is physically a lot bigger.
What was the predominant gear for most of the run?
Now slap two turbos on it! :-D
Maybe the forced induction will blow those face diapers off. Lol
Don’t forget the wings lol
Then jack up radiator cap put a diesel under put cap back on no more issue
And watch the rods shoot through the block!
Or a Procharger!!!
You guys always have 37s so that would make a big difference
The battle of the 7.3s
Man that truck works good. And all of that on a 87 octane tune, would love to see what they could do with a 93 octane tune as far as power goes. My truck has been tuned by these guys since it was pretty much new. I waited for the break in period, and then through a 91 octane performance/ tow tune on it.
At the higher elevation 87 is close to premium
@HalfShell if 87 is required going higher isn't going to gain you anything unless you tune for it.
That’s true, with a newer more modern turbo motor, the computer will automatically adjust for the higher octane and you will see higher horse power. But with those old pushrod style motors you won’t see any difference unless it’s custom tuned for it.
During those tuned runs, they should NOT have adjusted the tire size because they would be running the tests at different speeds.
