My understanding is that the transmission upgrade is more for off-the-line torque demands and I believe that is why RennTech throttled back on the tuning specs. Having said that, I spoke w/Renntech about the specs and they said they will still flash w/the original specs if asked.
Renntech - but stock is best...
Press in major magazines and media is all about advertising dollars.
Maybe even more. Brabus is one of the, if not the, most expensive mod company.
