Also the transmission peak rpm shift logic is based on a predicted RPM rather than actual. It takes so long to shift , the TCU needs to predict the RPM rise.
Bouncing off an RPM limiter could be problematic.

Thanks for your input, it doesn't seem to be a popular thread. What is the soft limiter? My understanding is that there isn't one, only a hard limit just before 7k rpm. I can rev to redline in neutral and every gear when in steptronic / manual mode. I've seen a soft limiter in newer Audi's that only allows ~4k rpm in neutral, this doesn't seem to be the case with the N52 + GM 6L45 combo. Please correct me if I'm wrong.
