Yo J, I truly appreciate your content because you definitely give an amazing breakdown instead of just showing numbers and being able to hear your input as well as other’s opinions and experiences is super helpful. Keep up the amazing work bro! #S58GANG
Thanks man I really appreciate it
I have tried both JB4 and Race chip and I honestly love Race chip. You can definitely feel the smooth power gain with Race Chip rather spiky power with JB4 which made the car feel like the F8X gen
Good input
@@WhatsyourForte awesome review bud
If u log and dial in map 6 u can tune it however u want with jb4. But i agree the off the shelf jb4 tunes are not goos. That said, i dialed in mine to feel pretty much like a flash tune in terms of smoothness but im not pushing the power limits
Interesting. Have you tracked the car with either? I remember my F80 not liking the JB stage 1
@@evanescent0311 I won't track the car but what I know is that the car was all over the place up to 3rd gear even with MDM on while I had the JB4
How do you not have more subscribers....you put out great content regularly!
Thanks man. I don’t know why I don’t but I will keep trying.
damn that isle of man green is stunning. the drop, the spacers, the lip....straight fire!!
Yeah it is a good looking car
visiting this 2 years later looking for a piggyback for my g87. great content and analysis!... one thing to keep in mind on the rwd cars is that the jb4 power spike at 3k may cause loss of traction making it slower than the more progressive power delivery of the race chip. also, I believe jb4 allows you to limit boost in lower gears to avoid this.
Thanks… yeah if you like to play around more JB4 offers a lot more customization. You can also work with them on custom maps

Yessir
The only serious drawback is that you have to connect it to the OBD2 port for it to work. All other analogical piggybacks on the market had it engineered it with no obd2 requirement.
Yeah that’s the one thing I don’t like about JB4. But doing that allows you to data log and has other benefits.
Great comparison vid Bro, in the end I'll say it's preference for whomever will want either device.
thanks, yep
I don’t have any tuning experience with RaceChip, or JB4. I’ve been tuning turbo charged cars, since the mid 1990s and to my highly untrained eye, it “looks” to me like the JB4 chart being all over the place, is it trying to control the waste gate. That’s really the only thing that makes sense to get this kind of spiking. The RaceChip is clearly better at controlling either the map sensor or the boost solenoids.
The JB4 is trying to control the waste gate where the Racechip is trying to control the cam sensor. You can fix this issue with the JB4 by running a custom map
@@WhatsyourForte ok, good, so, I was pretty close. 🙌
@@WhatsyourForte No, the Racechip is getting RPM by the cam signal nothing else. You can ask them yourself.
Would be good to see the DRF files and compare the actual STD VS SAE and smoothness of the charts.
Really REALLY good analysis putting the Racechip up against the JB4. There are a lot of variables that also need to be looked at and I feel like you touched on all of that.
With another dyno on your car with the racechip in efficient I think we will be able to see a better overall picture.
These cars are just not consistently responding the way they should be. We need a piggyback that is able to consistently put up higher numbers on the most aggressive driving setting.
I feel the same about running “E” I will never use it so I’m more interested in what the car can do on 93.
Thanks. Yeah I plan to hit the dyno again soon. I think with the way the piggybacks work you will never get 100% consistency. A true flash tune will be the best option.
Great detail and review. Thank you!
Glad it was helpful!
I thought with Atleast the air intake and base specs of the g80 comp. You would be running more than 500hp at base. Loving the car and can’t wait to get mine.
That intake is an early production model. That could effect numbers. I dyno'd more than this amount with my MST intake base.
Jb4 well be going on my 2022 bmw m4 competition this week 🤙looking forward to it
Enjoy the gains
Very informative video bro. Thank you!!
You are welcome
2 year engine warranty from Racechip makes this decision easy.
Solid work man!!! Thanks for the distinguishing the two and the analysis of the results.
Thanks man.
I read most comments, maybe it’s just me but are the Dyno numbers WHP BHP or CHP (at the crank). Great video and analysis bro. I’ve got ‘23 Comp XDrive and considering one of these tunes
These numbers are at the wheels
@@WhatsyourForte thanks
Great info bro😎👌🏽
You are welcome
Outstanding video!!! Trying to figure out the best option for my x5m comp. JB4 or Racechip. Only mod so far is resonater delete.
Solid numbers 👍🏿
Only tune I want on my G80 is from Steve Dinan. I just listened to his interview on TheSmokingTire podcast and his comments about tuning were very interesting, makes me question most tuners.
Dinan is conservative so that is why people don’t use them. The only benefit is that you can buy the matching warranty. I don’t think they are doing anything special. They just give you a little bump safely.
@@WhatsyourForte you should Check out his podcast interview. He goes into depth about how to do the tunes w/o damaging the engine. Apparently a lot of tuners don’t know how to do that.
Great work this seems safe to do both JB4 and race chip with out causing long term issues. I still dont understand how NVM mabz hitting those numbers with race fuel is it actually sustainable long term or disaster waiting to happen 🤔
You would only need to run one or the other. NVM had an unlocked ECU so he is able to tune the car.
jb4 makes ur engine a ticking bomb
@@wErikwSusan how do you know bro?
Great video bro....and honesty and clarity. Being this is now 19 months later....if you were doing a Piggyback, would it be JB4 or RC Black GTS for a 2022 M4 Competition Convertible? Also due to convertible and not wanting any fumes in the cabin, what is best 'bang for buck' mod you would consider to enhance power somewhat? Appreciate your wisdom and advice.
Thanks. If I was doing it now, I would go Dahler or Racechip for pump gas and if I wanted to test out E I would do JB4. These are the best bang for buck mods you can do.
Numbers increase is about the same on my stinger......healthy numbers.
Yep… those stingers are no joke… I really like the way they look.
Thank you for the great content 🔥. Could I ask if installing Race Chip would void your warranty? Would BMW be able to tell you installed it?
Thanks, Some say they can tell and some say they can't. I can only say that I had warranty work done after taking off the racechip. I think it depends on what you need done. Like if your trunk stopped working they are not going to look to see if your car is tuned. If your engine blows up, they will look.
@@WhatsyourForte Thank you for the response!
@@WhatsyourForte Thanks for the info. Was the warranty work a result of the racechip messing something up in your car?
Amazing video, appreciate your explanations! Quick question about the difference between efficient and sport +. So even with no tune, leaving the engine in efficient will produce more power?
I don’t think so. Only with the piggybacks would you have this issue
By chance do you know if you still need to run the car in efficiency mode or has this been fixed? I want to run the JB4 on map 2 but rather get a race chip if I can’t run sport+ and get full gains on the G80 M3 comp xDrive
I am always hyperventilating on the dyno.. I know it will be ok.. but still just have seen videos of straps failing, other nightmares. Yet back I go for dyno tuning in probably a month.. lol
Hahha well I watch them so I make sure ever strap is touched 😂
@@WhatsyourForte it's probably good I don't take my blood pressure every time my car is on the dyno. Lol
Great review… I assume the numbers are wheel horsepower and maybe tell us what kind of fuel. I always add a little E85 when I take the car to the dyno to ensure no KR usually I’m running E15.
I just installed the racechip and I’m going to do a dyno run to see the results.
Thanks.. 93 octane for both cars runs. My car is RWD his is Xdrive.
Did you do a dyno run?
is the part really good does it really add to the extra power can you feel the power? 100-200? I fill up with 102 octane and drive series with my M4 XDrive 100-200 in 8.2 seconds
And ??????
Id be very curious on the numbers if he had the exact same mods as you. Having a down pipe could very well level out that spike..
Going back on the dyno this Friday. We shall see
when you say efficient, is that the same as Eco Pro? Also, does this throttle staying open thing apply with Racechip too or just JB4?
On M cars efficient is the lowest setting on non M cars eco-pro… they don’t put eco-pro mode on M cars. So efficient in a M car is equal to the level above eco-pro
Thanks for the great review. I was stuck between the JB4 and racechip for my M.
Does this void warranty? I don’t own a bmw yet but I’m curious cause I’d most definitely get the jb4
There is a long debate about this. Some will say yes, some no. Talk to your service team and then make the best decision for yourself. Dinan also has a piggyback now
so if youre racing and need maximum power, you'd need to be in efficient? what is the point of sport plus mode then lol
With a base car sport plus is great. With the way the piggybacks work by trying to fool the car you run into this issue. When a true flash tune you would not have this issue either.
How's the racechip holding up? Amy issues? Did you change your spark plugs?
Racechip is doing fine. No issues. No I have not. It was not required or recommended to do so
Hi, nice video man. Does the car have the stock exhaust?
This car was stock outside of intakes
I don't see the concern with the spike in trq. If anything the spike is going to make the car feel faster around town.
Maybe concern is the wrong word. Smoothness is the correct word. I want to see what difference it will make on my car dyno'n in efficient mode. It made a big difference on the Jb4
@@WhatsyourForte did you ever make a video of doing the dyno run in Eco mode for jb4?
I thought on the jb4 you cant go map 3 with 93 ocatne? Dont you need e30 for that. isn't map 2 the highest for 93 octane
Hello. I didn’t understand if efficient mode has more power for dyno only or road use as well?
Ok,, in that case ,, run your 0-60 and 1/4 mile on efficiency and sport plus to compare to what you're saying which puts out more hp on DRAGGY. Run times etc.
In a later video I ran my car on the dyno to test how Racechip reacted and it was the same Hp. For some reason JB4 seemed to be more effected. When me and this owner did a 50/60 roll we where dead even
So....Dumb question...All the talk of HP/Tq improvements and Dyno's the question is does your 0-60, 1/4 mile and mid band/passing numbers really change significantly with the Race Chip? I would be very interested in trying a RaceChip but only if I feel and see the difference on the road. What say you? Thanks
You can definitely feel the power increase on the road. Racechip tested the 100-200km. They got 7.67 stock and 6.37 on top map.
0-60 times is going to depend on grip. Anytime you add power you need more grip to launch.
@@WhatsyourForte Mine is a 2019 BMW x5 5.0 AWD so I am hoping grip is never an issue with brand new rubber on 21s, that being said I just took the plunge and ordered a RC Black with app! RaceChip is having a flash sale (no pun intended) and they were 20% off! Your video, 20% off and 30 day return policy made it a no brainer. Looking forward to see what $700 buys me in way of performace.
whats efficient mode?
hey man you been driving with the jb4 since this video? worried about the longevity
The owner sold his car a little after this video and got an M8 grand coupe
Your RaceChip runs had more smoothing applied than the JB4 runs, the JB4 seems to spool almost 500rpm faster, while not being turned all the way up. I'd say the JB4 wins all day, but that's just my opinion.
So if you look back at my downpipe dyno video I posted the same dyno chart on smoothing 3 just like the JB4. The Downpipes really smoothed things out on the chart. I have to re dyno again in efficient mode as all of my runs where in sport plus and as we see you don’t make as much in sport plus. Once I do that, we will have a better picture of what is going on.
@@WhatsyourForte I'll be interested to see what's going on. Before JB4 came into beta RaceChip were really out pushing their product quite hard on the forums but when the JB4 Beta program released they disappeared. Happened to early MQB as well, can't believe I've seen it happen twice. They do a hard push early to get their cash while the true competition is sleeping, there is a reason there's only really flashes and JB4'S on the dragy leaderboards.
Let me guess? You have a jb4
@@DanJLeh What "Dragy leader-boards" are you referring to? The one in the BimmerPost forum (g80.bimmerpost.com/forums/showthread.php?t=1855856) only has 5 (presumably running JB4). Additionally, most people going for the RC just want the extra power without trying to push the engine with the JB4 and the different ways you can tune it. Therefore, their interest to be in the "leader-board" would NOT be there. I personally would have bought a JB4, but the opportunity presented itself where I was able to get an RC for less than 1/2 the price. Not bad for just wanting to get rid of the EPA and emissions restrictions and open the S58 up a little more.
Anyone know if Race Chip removes the Speed Limiter?
Nope. You need a true tune to do that
I would like to see what your M3 would get in ECO mode?
Next Friday I am testing it
@@WhatsyourForte I have a B58 and I have the racechip but haven’t put in on yet
@@youngover4030 yeah definitely test is out to make sure you are getting what you paid for
@@WhatsyourFortedid you ever test the Racechip in efficient vs sport plus?
@@WhatsyourFortedid you ever test the Racechip in efficient vs sport plus?
New to the performance world. I have a 2020 Q50 Silver Sport. Since I don't have any experience with maps (just actually learned what the term means), would you recommend a racechip instead?
Question 2: If I do go with the Racechip, I am looking at the GTS option. Will that be a safe option (for my engine) v. the RS option?
Racechip is a little simpler to use. Since this is your first time, I would recommend them over JB4.
Can BMW detect the jb4 or racechip when taken in for warranty work ? Even if you removed it before hand
I have been told if they want to dig and do enough research I think they can. They can only deny warranty work on the engine at that point. I am not worried about the engine on this car.
Do you keep the racechip in map 7?
All the time
wow that's crazy efficient 20 more hp/tq. i usually drive my M2c in sport (sport plus too obnoxious with cracks and pops in exhaust and too twitchy with DCT in first gear), but i've always noticed how when I drive in efficient it seems to pull as hard maybe harder
Yeah I think this is with the JB4 due to the throttle closure issue. When I did the same test on my Racechip we did not see that much of a difference
Did you ever hit the Dyna again?
Off topic but what is the suspension setup on it? Looks sweet!
It sits a little lower because it is strapped on the dyno but it is H&R springs
Are JB4s traceable now ?
If they want to find out they can. Depends how much work they want to do
so if you want to drive it fast as hell, you should out it in efficient ?
On JB4 it seems that way
What would E numbers look like?
I have seen the E numbers in the low to mid 600s with custom maps.
@@WhatsyourForte Seems like a big pita just for more power. Lots of variables. Give me something that runs solid on 89 and even better on 93 that way your never worried about crappy octane..
93 octane 💩 here in Britain we have 99 upto 102 octane with octane booster 105/107
Race chip all the way!... way more linear and to me safer...
Yep if you dont want to do custom maps on the JB4
what suspension is the green g80 on?
Full review coming soon but he is running H&Rs. He doesn’t think the rear is low enough tho… it looks really low on the dyno.
@@WhatsyourForte damn didn’t think hr got that low the front looks perfect
M2 g87 racechip +90 cv 😅
Maybe they have improved it
So, how much power did it gain?
You mean over stock? I go over the dyno numbers at the end but stock was around 490
Is that a base M3?
M3 comp Xdrive
@@WhatsyourForte thanks
So which one do you use right now?
I was using Racechip. But I am currently testing out another one. Video coming soon.
Have you sold your jb4
The owner of this car did
Did he switch to a flash tune or racechip?
All it does is increase Boost 🤣
For the most part. There are other things but that is the major point
Bringt Race Chip was ?!
Racechip is good
is the part really good does it really add to the extra power can you feel the power? 100-200? I fill up with 102 octane and drive series with my M4 XDrive 100-200 in 8.2 seconds
Race Chip gut ?
I am not sure I understand
