I have a 08 G8 GT with a 434 stroker. 500+ whp so power is not the problem. When I try to power brake in any of the trans modes(Drive, Sport, or Manual) with the ESP of the car holds at 2000 rpm. I have even tried rolling a little then applying brake and the car stops and straight to 2k it goes.
Is this in the Brake Torque Management?
Would it be alright to disable the torque management all together?
