W212 E63 S 4Matic runs 10.3@130 in the 1/4 mile with Pure Stage 2 M157 turbo upgrade and meth injection

Renntech says they have this solution...

trust me bro, I wish it was true but their TCU tune is not much different than Weistec's valve body upgrade.... its just increases line pressure and quickens shifts, but doesnt address the trq limits.... that's probably why they limited their turbo kit to 700 whp as they probably found out the same thing we are seeing here with the pureturbo upgrade that the extra hp isnt getting transmitted to the wheels

so far only people that have cracked the Trq limits in tcu, from what i heard is GAD, but that's not really a realistic solution to any of us in north america to ship our cars to germany just for that especially when we still dont even have any real world track results from gad (they make a ton of power on dyno but what track timeslip does that equate to? )

Agree 100%, I have tried 4 different brands, including the stock trans and clutches... So far the stock is staying together where the others didnt.

As far as the TCU being the restriction, not too sure about it.... I don't consider it to be the problem, Computers can get tricked with some math, the limitation in the TCU is based on what the ECU reports; you make the ECU believe its making less power, the TCU wont limit the power. The one thing you cant fix with the laptop is the clutch, by experience I can tell you, doesnt matter what company's stuff you get, not one held the +800whp +900wtq... Everyone rushed and they all came up with a product that is worst that OEM, no one was really pushing this cars till recently, within the normal power level Under 750whp they hold, but so does the OEM.
Now, if you think about, AMGs M157 are not the only ones with problems putting the power down, BMW's
F-chassis S55 have the same issue, and limitations, upgraded clutch doesnt hold over a specific WHP level, Lighter car and rear wheel drive. Realistically, we ask way too much from this AMGs, this cars are doing way more power than most cars currently on the market, with nominal amounts of mods and money invested... and lets not forget the weight factor making it even more unfair to compare.

I believe the real problem is, not having the support and the attention that all other cars get (GTR for example), from the community and manufactures, is what really kills this cars; handful of companies making parts for them, and they seem to not really care about their products be as good as the should...

In the mean time, as far what we are trying is to get that pass we need, car has plenty of accessories and components that will make up for couple hundreds LBS... Starting with me not being in the car, and have a lighter individual drive the car is a 100lbs less already out the equation. A different wheel and tire setup and some track tuning should give us the results we are looking for, even keeping the car at a lower setting it can be done, just by going by the trap speeds we have seen so far.

I don't know. The Dodson DCT upgrades seem to be working well on high power BMW's. Different trans.

They have their limits, ask me how I know lol, just had one slipping the dodson clutch down the track yesterday... By any means Im saying they are bad, but like anything else has limits... thankfully it always can be improved, just need the time into it!!!

I agree the way around the tcu at the moment is tricking it, stack a piggyback to increase boost over the flash tune to the desired power level

pretty sad that there isn't a clutch kit that worth a damn, I'm assuming you tried the exedy ones that were mentioned in a recent m157 eurocharged turbo post.

+1. Still waiting, and my car is 100% bone stock.

^+1 ... whoever figures out a solution to the TCU intrusion will be getting a lot of love from the M157/722.9 MCT crowd as we are all waiting, and willing to hand over cash, for that solution... I know at least 6 guys (myself included) that want to do turbo upgrade on M157 but waiting for a tcu solution that prevents it intruding and from cutting out all the extra power

How is GAD doing it supposedly?

How is GAD doing it supposedly?

honeslty Im not sure about it as all i heard was they could do it, but didnt look much more into it as it was not a viable solution for me when i had my e63 as they needed it in house in germany to do it.

since then i moved on from the W212 E63 platform as it was going nowhere other than a few one off projects that still cant run faster than a stock turbo RS7

have you seen GAD's results on the race1000 standing half mile event in Germany? that should give you a good idea of their times, shouldn't it ?
