TCU TurboLamik

hello, I have a problem
I have an e92 with m50b29 turbo 8hp70 and I can't rev the engine in transbrake, I can't reach the launch control rpm more than 2300rpm, it doesn't rev no matter how much I press the throttle
With virtual clutch its very abusive for the transmision

The tcu does not limit the transbrake rpm in any way. The engine is revved as much as the converter and engine power allow it.

You can use launch control instead of transbrake
