What is the max. Power that was measured with an JB4?
Performmaster in Germany achieved a reliable 460PS for the Facelift with Guarantee.
With their own piggyback
Maybe im missing something but "Performmaster" website shows 430hp. Doesnt mention anything about working guarantee with the 19's. In fact, if you select C450 or GLE43(the only options) it brings you to the same C43 page which states "Currently not available for Mercedes GLE43 AMG". Not sure why this would be the case since its the same motor. Probably the same reason they dont list the C400 on their site... I also dont like that they are not upfront with the pricing, i dont see it being inline with the JB4 costs though. Not saying BMS is perfect either, but for the price i couldnt be happier with mine.

Prices for the Optik-Paket are on the Website.

So beside having a Guarantee its also legal in Germany and developed by Germans, that have an Eye on driving Topspeed for a longer period of time. I'm always Scared US-Companys programm stuff to do funny 10 second pulls and then go back to 80 m/ph cruising.
Often when i'm driving to a Customer thats 400 km away i'll drive throught the Night and be at the Speedlimit for 60 minutes straight.
So back to my basic Question: You get dyno'd 460 PS / 610nm with the Performmaster, what numbers are the JB4s pushing on certified Dynos? Any similar to give it a thought?
BMS,
I spoke with you online support yesterday but still have a few "novice" questions. Is there an easy way to get in touch with you guys? Would like to place my order this afternoon please.

You are bang on right about testing the car at top speed part. North American cars are not concerned about this at all. There are quite a few C43s with ECU tunes that blew the turbo when going to the topspeed. I will trust performaster over any other piggy back tune for the C43 in terms of peace of mind. Specially if you are driving at very high speeds for extended periods.
I am using the .com translated version, but yes same site. Must be a translation error as for me it shows 430HP. Still see nothing on price and Warranty only applies to Germany, Austria and Switzerland, which makes sense as they are based there.
I would agree there are some tuning companies out there that want to just have the best dyno number or best 1/4 mile time so they squeeze out everything from the ECU to get this, but reliability goes to the waist side. You cant get that with any piggyback as the ECU safety parameters are left intact. BMS or performmaster will be a safer option. As for who has best dyno, thats a really subjective benchmark as every change in weather, setting, dyno brand, fuel, or fan speed will effect the results. There are no standards im aware of that you can "certify" to. Real world testing with my BMS shows significant gains over stock. and 1/4 mile times are inline with cars of the same weight that put down 430+HP.
That said, im sure performmaster will give you good results too. I just see some flaws in how they are trying to market their mods that, for me, raises some flags. Im also not aware of anyone with their tune.
EDIT: It looks like on the .de site there is a 2018+ C43 page with the 460hp rating due to the "390hp" stock. FYI 2018 is still 367, 2019 is 385.
I reached out to Performaster last year because I was traveling to Germany frequently for work. As of March 2018, they wanted 2267€ plus VAT (about $2971 US total) and would only install on Euro-spec cars. Unless they've changed their tune, or whoever is looking is actually in EU, you're SOL with them.
BMS,

You're more than welcome to email me directly if you have any questions or concerns.

We continue to ship at least 10 C43 JB4s per week many to 2019 owners and we've had very positive feedback. We've been suggesting BCMs for the 2019+ models just to cover the bases.
@MatthewJ i think we may have found the difference, i was checking the side for the Facelift, where they claim a 460hp.
The Price i got from them was similar, of course this is only interesting if you can use the Warranty, so if you're based in the UK, Performmaster may not make sense for you.

If you want something thats mass marketed, you can still go racechip. They have the same claims. You know that right? And racechip is like 700usd.
LMAO at 3000usd for a piggyback....LMAO....just LMAO

And yet, i still haven't got a single answer about if someone used a JB4 to drive topspeed for 60 minutes.
Not saying its worse or anything, i'm just not getting an answer.

btw. you pay for the 2 year Warranty on top.
Most JB4 users are in US where the cars are locked to 215kmph.

You can ask Racechip if their unit allows you to drive at top speed for X-amount of time.
Before I got the BMS I emailed racechip a bunch of times.they responded every time and answered most of my questions to my satisfaction.
The performaster unit just sounds crazy crazy crazy overpriced. I think most people are just looking at the 460hp claim and losing their minds. Not realizing that even cars that Dyno'd 390-420whp, most of them still trapped 116-118mph in the 1/4mile.
Thats AMR/EC/BMS JB1/4 Units. 99% of all users still trap under 120mph. Only like 2-3 users have ever trapped over 120mph ( and 2 were stock turbos, only 1 of those guys were on larger turbos and his trap was like 120.X) that I can think of among all of the Tuned 43s out there. Both piggyback AND full remaps.
AMRs own youtube channel which features their C43 that dynod 420whp or whatever still only trapped 118mph. And thats supposed to be like 500bhp. Basically the same trap speed as cars that use JB4's and EC tunes which both also trap like 118.
Even the JB1 that only claims like 420-430BHP still trapped like 115. 18Bora was able to trap 118 i think.
Infact if you look at dragy, like 95% of the C43s on the history board trapped like 116-118 regardless of how much BHP their tunes are supposed to be making (which can vary wildly from 420-500bhp). And only a FEW of the cars that trapped 118-120 are full remaps. The rest were all piggybacks. And I did not see any of them list performmaster as their tune in the mods list.
Performaster is just crazy crazy overpriced.
The C43 as it stands has 2 very very large bottlenecks.
1. Gearing
2. Some of the internals are weak.
Even the few cars that have upgraded turbos (which cost as much as that performmaster tune btw) STILL only seem to trap about 120mph.
I think there was also a Racechip guy on dragy that trapped about 117mph and that unit only costs like 700. They also claim to have a warranty btw.
Basically, IRREGARDLESS of what you pick, AMR/EC or Racechip/BMS/Performaster or whatever. You will probably all trap roughly the same speed lmao.
Even if you upgrade your turbos you still have a 90% chance to lose to some dude on a JB4 running a 200USD meth kit.

No you can't remove the speed limiter with a piggyback system. And even if you could, the trans and DSC modules would still store true max vehicle speed, so lease returns and warranty claims would get awkward quickly.
Customers 2019 JB4 + BCM log from today... 12.0 going up hill. Customer provided the screen shot so don't know what trap is. But either way for anyone low on boost having direct control of the wastegate solenoid is the solution.

What map is this? With the BCM, isn't the boost suppose to hold better? Boost curve looks like mine w/o the BCM.... Black Diamond slope...

Map5 that run. The BCM allows us to dial in more wastegate dutycycle directly. With this 2019 he was making around 2psi less down low off the line hurting his times. Something appears different on the launches of the 2019s. The BCM allowed us to get his boost back up down there. Of course, we could crank boost higher with more aggressive BCM settings. Working with customer on that now.
Also next firmware version I plan to redo the map numbering, so map8 is the VALET map, and maps 3 and 4 are performance maps between map2 and 5.

Do you think we’ll be able to get back the boost from 1500-2500rpm like the pre-2019 cars, or is it inherent with the newer turbos.
