Vehicle Information: Model : Cayenne S; Year: 2004; Mileage: 10k;
The cayenne has a serious lag in acceleration response. I am thinking it is the electronics. When PSM is on, it kills the gas when the brake pedal is pushed. There seems to be a lot of electronics going on. I want to control more of the car. I turned off PSM and it had better throttle response but revved higher. I want to control the car. What should I do? Thanks
