Look, in current times the mk8 is expensive and it's looks are controversial. Most enthusiasts are looking back in time. Mk3-4-5-6-7. Maybe get back to the roots, hit some OG tuning points for mk3 and 4 since they're the most economical at the moment.

Love the mkviii content. All your content is high quality and entertaining My thought on the low view numbers may be not many of us have a mkViii and those that do may not be ready to do mods on a car under warranty.

I was really looking forward to this video. Like I mentioned on an earlier video I have 20k+ miles on a JB4 on my 2016 S3. Luckily I have not experience any breaking up issues with it. However, when running one on a 2013 328 I would occasionally feel the car buck or hesitate when slamming onto the throttle. But when rolling onto the throttle it was fine. S3 has been solid though, at least in terms of feel, I've not taken it to an actual dyno yet.

I think it comes down to whether you want to play the TD1 game with VAG or not. I used a jb4 until warranty ran out and then got a proper flash. But I also got a turbo replaced under warranty when I was using the jb4 and didn’t get flagged so that is something to consider with new cars if you don’t have a lot of extra cash to burn

Glad to see some content for the JB4. I bought one for my 2014 1.8T Jetta. I then transferred to my 2019 Alltrack a couple years ago. I have over 50k miles on the same JB4. Map 1 or 2 with +4 or +5 psi I bet is much more noticeable (via butt dyno) on the 1.8. Yes, they aren’t a cheap option, but the flexibility to easily change map, make a custom map, and the logging feature to review what your boost/IAT/timing/fueling is doing during a run is what sold me. You can even transfer it to another car with the same engine or resell it which you can’t do with a tune.

I've been watching your older presentations looking for Mk4 content. Recently rescued a '03 Jetta wgn. (2.0/5spd.) from going to the recycle yard and am trying to find the "weak" spots of it. Replaced the dipstick funnel, pressure vessel cap and put a battery in it. Runs strong with 270k and continuing to find defects and worn out components mainly small molded hoses, secondary air pump mounts and plugs. You've got a real good video presence and enjoy your videos.

Was always skeptical about intakes. Thanks for showing us proof!

As someone who has a MK8 GTI I love your MK8 content! That being said I would say that views might be tanking simply because the MK8 is so new Its not exactly easy to get one at this point with all of the shortages. I've had my MK8 for 7 months or so and I still have not seen a single other one out on the road yet.

great video! Thank you! Can't wait for the APR Stage 1 for the MK8, but this just might do the trick until then.

Good video. I have had JB4s on a few cars and also now correctly on my ‘22 Rubicon and love it. Next is WMI and map 7 :) which just arrived last week and waiting to be installed.

I had a JB4 with the E85 flex fuel adapter in my 335i N55 for quite a while. Made a massive difference in torque and power. Especially the auto tune map which kept getting stronger the more you pulled. Wheelspin in 3rd on a dry road in souther california. 😁

Terrific video and review. There is nowhere else to get this kind of info on the piggyback tune. With a GTI under warranty, I've always wondered if this is the warranty-safest way to go.

Thanks for the video, been thinking of a tune or this for my 2020 gli, will probably save for a full flash and a clutch upgrade bc I heard they don't like much more than stock power.

That pulsating power is a killer. And often these "kits" makes the fuel consumption much worse for a little more HP. It looked like a good an promising kit at install and the app but is the car starts to vibrate is no good. Also when it potentially fails it can easily kill the engine by running too lean. Never trusted these kits as ive had a few cars in for diagnostic for heavy smoke, low poer or no start and it's been a tune box (they're generally not watertight so many rust out on the innside shorting out the wires) My dad also bought one for an old VW Caravelle and it got more HP yes but used twice the ammount of fuel, was roalling coal and uneven. Complained and got a proper ecu modification and the car was 10 times better and smoother, no smoke and the gearshifts also got better

China "tuningbox" can't really be compared to JB4... a proper tune is the way to go..

I've used a few piggyback tunes, they're "good enough solutions" but after getting a true ECU tune from one of the big name tuners I wouldn't go back. A proper ECU tune coupled with a a TCU tune is so much smoother and refined it's incredible. Besides, a piggyback is not undetectable. If the dealer wants to they can start looking through the logs in all the various modules and see if any of them were either requesting or reports out of bounds values for things like boost, torque, etc. A cursory scan won't show anything out of place but if there a large dollar warranty claim like a turbo or piston rings, the dealer will be doing a deep scan on everything.

*Interesting to see the results on this what a predicament* 😃

Cant wait for proper ECU tunes. Also, thanks to this video I think ill be purchasing the R600 intake soon for my Audi S3. In terms of content, id love if you could do a Golf R vs S3 8Y content. Specifically, dyno. Thank you!

I was pretty pissed about the hidden costs like you were so I agree there. It really has it's own merits and subtractions. One thing you didn't mention is the ability to resell it which is a huge plus and the convenience of tuning yourself without going to a shop/tuner is big too. Anyway I wouldn't hesitate to recommend a jb4 under the right circumstances but like you I prefer a professional tune by one of the major companies.

Hey Humble mechanic. Awesome video on the piggyback tune.

Overall its been a great upgrade for a cheaper price and continue the great informational video's.

That's some solid advice, right there

You have to drive the car so it can calibrate the piggy back and understand what's going on. May take up to 10-20 miles of normal driving. I've had jb4 for over 5-6 years and I love it .

I’m a happy Mk7.5 GTI owner, and although I’m not a fan of the Mk8, solely bc I won’t accept what VW did to the infotainment/haptic-touch controls on this generation, I did find this content helpful and informative. I’ll be adding a Stage 1 EQT tune with Cobb AP soon though! Def enjoy your channel’s Golf content regardless of GTI/R or generation🤙🏼👍🏼

The face alone that the guys made at the tuning shop when I asked them about the JB4 was enough to put me off of ever buying one. This was when we were already in the process of flashing my car flashing it to Apr stage 1 6 years ago and I was asking about stacking for my daily. I still would never put one of those spoof the numbers piggy back boxes. The ecms detected them back then and they detect them even better now. Also love the rotating r center caps

Great video.

I have a TDI tuning box on my mk4 golf GT TDI, i did notice it was more responsive. My golf is box standard engine wise and according to the “website” my HP should rise to 150 from 115. Ive driven a 150 pd TDI its no where near, but there is a difference. But i did notice with the engine running I can’t communicate with the control unit using VCDS so couldn’t read injectors at idle, i was intrigued. With ignition on can communicate with no issues and there is no faults present. Haven’t tried with ODIS yet though

I had so many issues on my 7R with my jb unit when on the race track, constant limp mode and they had no fix for it back then, hopefully they fixed it by now

Neuspeed piggyback on my mk7 definitely added some ooompfh during the warranty period. APR tune definitely better though.

I’ve got a lot of experience with jb4 on a e92 335i with an n54 and on that platform you can combine it with a mhd backend flash. This gives you the best of both worlds, jb4 map switching, safety features, anti-lag etc and the smoothness of a flash tune. I wonder if anything like that will be made available for other, newer cars 🤷🏼‍♂️ Another thing to note is that on the n54 cars you connect the jb4 inbetween the dme(engine ecu) and the wiring harness from the car and everything is contained in the factory ecu box so you can’t even see that it’s installed 😁

Our standard diesel is 95 octane. The auto is DQ500. Do you think this tune on this engine/trans is durable? Best regards, Tore.

I kept getting ads for Race Chip. I'm curious about your thoughts on it. Ultimately went with APR stage 1.

Does the MK8 version of JB4 not allow you to log and compare actual data from map to map? I wish that was included In the video. You’re well aware dynos are “tuning tools”, would’ve been nice to see you track Down the dips on the dyno chart and break it down on the log to better explain to the audience what the car was actually sensing/reading and how it was reacting.

Whatever it is, the Ecu is compensating or cutting off something as you say and going into feedback loop. That would scare me too, you can knock your pistons to bits. You just got this beautiful car….I completely agree that a custom tune directly in the Ecu is the best. Also I’d rather run slightly rich than lean to be safe. Air intake numbers, who knows, maybe the stock injectors are higher capacity than needed and the air flow happens to be an excellent match with the stock turbo. If the Ecu says GO! and the higher air flow rate is kept up nicely by the turbo and the injectors, there you go.

Mk4 are in alot of enthusiasts' hands now. Ill watch too much of it. Im Excited for the TT series.

I think the issue based on your dyno graphs is that the developers of the JB did not fully understand how to handle the turbine sensor which is new for the MQB platform at that time. Fast forward to 8 months later, I wonder if anyone could redyno their R/S3 and see if there was any progress. The JB4 on the MK8 GTI which does not have this sensor seems to do what it should, add about 10 whp per 1 psi boost. I've been running JB products since back in the N54 days when the JB was called the terry tune and was a geek named Terry who thought piggybacks were a ripoff and set out to develop a similar solution with Radio Shack parts. Time flies!

Sir aside in upgrading the turbo on mk8 gti what else is needed to be upgraded?

HumbleMechanic I have been having issue with my mk5 jetta with a 2.5l auto. I've been going through and repairing common areas for vaccum leaks or may cause incorrect reading to get rid of the p0171 lean code. I replaced my fuel filter, valve cover gasket and air lines that had been brittle on the intake next to the throttle body. I replaced the maf and cleared the codes only to have the car choke itself and shut off. Once the new maf sensor is unplugged the car will then run again but extreme poorly. I would like to know how to correct this matter before I rack up a larger shop bill giving my car to a mechanic.

Thanks for this. I had a IE stage 1 on my 16 A3 1.8 and after around 5k miles the exhaust turbine broke off. That tune was putting out 20-22 lbs. Maybe too much for that turbo. Returned the tune and got a Race Chip tune for $400 with the app to turn off and adjust for several different setting, eco, sport and race. Of course I always have it on race. It's half the power output of the map tune but I have more confidence it won't damage the turbo.

Are some end links too stiff for daily driving? Do the roll center ball joints make much of a difference? All of these are things that I'd love to know more first hand info about since the MK8 is a different creature than the mk7/7.5. Maybe the stiffer sway bars aren't needed with the torque vectoring diff? Anyway, thanks again for a top notch vid and I will continue to hit refresh, and regular check-ins for your next content.

I've got a JB4 fitted to my Golf MK8 R over here in the UK. I'm having endless issues in regards to how it's running, what feels like surging or hesitation between 3.5k and 6k in most gears. I've put it back in Map 0 for now until issues have been sorted

@@fungaming4k Well, they seem to have ironed out some of the issues now. I was having awful hesitation and bucking between 3.5k and 6k. We tried all sorted of adjustments on the map but nothing was fixing it. George sent through a firmware update last week which seems to have helped but now the car isn't much faster than standard after doing some dragy times. Also, I can't use launch control as the gearbox doesn't know what to do when it tries to change.

@@davidwakelin840 so still needs more work for mk8 golf r . . Testing . So I guess in time it might get there. Anywho I've been waiting on apr . But car is still locked . So the jb4 is only real opinion now. And I had jb4 on a bmw . Worked great . But yea bmw / burger is where it started. So hopefully 🙏 things come around . For the mk8.golf r . .

The real tunes will make you very happy once they come

Did you use the foam or cotton filter on the Racingline intake?

I recently got a turbotransformer (similar to jb4) for my 330e with the B48B20A engine. Logging with it disabled the car usually boost to 12 with some rare peaks to 14. With the TT set to +2 PSI I see it boosting commonly to 16-17 and some peaks to 20 which scared me since a tuner told me you enter squarely into danger zone over 18 psi with these engines. So I removed it and will wait until the ECU can be reprogrammed for this car.

One of the best features of the jb4 is its logging capabilities. You can dyno the car, and get data from the jb4 and see exactly how many degrees 9f timing are being cut around what rpms, if your afr is lean you can see that and back off appropriately.

Yeah but you can also get that kinda data from a cheap OBDII reader and phone app, or better yet VCDS I got a $11 bluetooth OBDII dongle and a $5 app and can log MAP, rpm, ignition and valve timing etc....

Hey Charles, if you start to lose the clutch, I'd be interested in clutch content. It would be nice to have a clutch that is very dailyable with no NVH. With my experience in the past with 6 puck clutches and single mass flywheels, I don't ever want to get one again. However, eventually I want to improve power in my Mk8 R. I've heard things about using an Audi clutch on the Mk7, surely that's an option for the Mk8?

How doyou feel about the STP Pro Valve Cleaner, Does anyone know if it works well enough to try it a few times??

Dont you have to swap to colder sparks to run jb4? Never used it , just heard it needs colder sparks

I have a JB4 for my Mini Cooper and it has been a love hate relationship but my Cooper is beating 8spd scats and keeping up with 10spd mustangs with just a downpipe pipe and piggyback. For what's it worth while holding warranty and being "stock" it's worth the buy

Want to do this before I get an AP but somewhat worried about my stock clutch. Mk7 6 speed with 80k miles

Those center caps looking good

Thanks. It my fav part of the video hahah

Did u have to tap into the O2 Sensor wire with the jb4?

I am not sure if this has been addressed for you VW guys. But I have been in the Beta program for the 2022 WRX JB4 for a bit now. An we have the ability to use Map 6 and dial in our own custom map. It is actually quite simple if you spend the time to learn what is what and what to look for on the logs. You can smooth out those graphs. A good way to look at it, is the Maps 1-5 are like a Cobb AP OTS map. They are okayish for what they are, and are built as a one size fits all type deal. Which doesnt always work car to car. But Map 6 would be more akin to a tuner making a custom map for the AP. Fine tuned to YOUR engine and exact setup. While I do agree, ECU flash IS the better way to go, SOME of these JB4s are still undetectable by some companies. Subaru it seems being one of them. So far we have seen 2 JB4 Subaru guys go undetected in Warranty claims. As well as a engineer digging into the ECU and seeing that the current version just isnt built to monitor the smaller things needed to pick up the JB4. Which I am sure will be addressed in the next model/s. BUT this is the internet so take that tid bit with a grain of salt.

One of the down side of Piggyback is the need to run the car a few miles after each map change to allow the cars computer to adjust to the new numbers for optimal performance. That’s why you probably got high numbers from stock when coming down maps.

Traded in my Mk7 Golf TDI due to the chronic leaking sunroof. Started causing significant electrical issues. But I got a MK8 GTI Autobahn CPO. 10K miles and 3500 cheaper than new.

NICE!!! This is why I HATE VW sunroofs!

notification squad, Have a nice weekend!🔥🔥🔥

I have a JB4. People talk Ish. The support team is great but the Docs scatter all over the internet which make understanding the product feel iffy. It works. and really works if you learn to exploit it.

I have done it with a stiff pick. but it SUCKS!!!!

I had a JB4 on my MK7 R and it made a big difference even with the base tune they put on it. My clutch though... man I never launched the car even once and my clutch was slipping badly on the interstate and the car had less than 9k miles on it. I don't blame the tune, I blame the VW engineers thinking that a GTI clutch would work on a car with 50+ more HP. Burger are legends in the BMW tuning community and will no doubt make good progress on these MK8 tunes for even more power and smoothness with the more aggressive maps. Hopefully someone gets these ECU's cracked before too long though.

Id also be concerned with how long the stock clutch will hold up with added power...mk7 needed a clutch with a tune....wonder if the mk8 will be the same way

I need some of those floating r center caps

A lot of Jetta guys including myself run JB4 on top of APR Stage1 w/ an Is38 bc we don’t get alot of tuning support from the big companies
