The 04-06 Porsche Cayenne is one of the only vehicles that requires the removal of the ECU from the car. Because of the ECU communication, OBDII flashing is not available. Once the ECU is removed from the car, you can overnight it directly to VRTuned where it will be bench flashed and then return overnighted back. The ECU flash will alter your fuel, and timing maps to give you a very linear increase of power over stock. For those worried about check engine lights, there are none! Once the car is flashed, the low end torque and throttle response will be much improved. The overall improvement of drivability makes the Cayenne S even more fun then it was originally. VRTuned can program your vehicle no matter what country you are from or what octane you use. We have different maps for those running 91 octane or 93 octane and higher.
