VR Tuned ECU Flash Tune Porsche Cayenne 958 GTS 4.8L V8 11-14

The 4.8L V8 in the Cayenne GTS is enough to get that vehicle moving and with style. Coming with an extra 20 more horsepower over the Cayenne S, there is still room to improve. Improving the vehicles throttle response and improving the pull throughout the RPM range is all part of enhancing the vehicle with an ECU tune. With our tuning, we are able to achieve a very consistant performance gain. Standard mode and Sport mode still operate the same giving you better throttle response. Adding other parts such as intakes, exhausts, plenums do not require a reflash and only improve the performance of the sedan.

Crank Horsepower Ratings:
