Xcede Performance of South Africa is the first tuner to surpass the 8600 rpm DCT limit.
Yeah I am a co-owner of Xcede Performance. We have managed to get a DCt to rev 9000rpm. In fact we can get it to rev pretty much anywhere we want. And I can assure you it's not easy. BMw have hard-coded the rev-limiter outside the flash area in the DCT DME. We had to be rather innovative to make it rev there. But the car does peak around 8500-8500. But the good part is that it does not drop off to 8800rpm. It's relatively flat. So there is a definite benefit to revving 8800, evein if it peaks a few hundred rpm before that.
