I have my car tuned for this tb and it still gives me ****. when i floor the car it shifts at 4500 and then when cruizing it doesnt want to down shift or anything. i put the stock tb on and it runs like a dream??? im clueless. FWIW when i shift the car manually it runs fine just wont shift on its own.
I just took the tb off my 99 m6 ta and it worked fine. Im using the same sensors so i dont think it could be that.
