The v8 in the Cayenne s which is shared with the panamera s, is enough to get that vehicle moving and with style. The v8 engine still has more power to unleash. Improving the vehicles throttle response and improving the pull throughout the rpm range is all part of enhancing the vehicle with an ecu tune. As tested with this Cayenne s on our mustang awd dyno, we were able to achieve a very consistant 20 wheel horsepower. 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:
stock power 400hp and 369ft/lbs
tuned power 430hp and 385ft/lbs

We do store your stock file if you ever want to revert. Because the ecu must be removed and opened, if you are concerned with warranty, you may want to speak with your dealership. Removing the ecu takes about 20 mins and we have provided instructions linked below. with the vr tuned ecu flash, basic bolt-on performance parts will not require a retune of your ecu. Adding parts such as an exhaust, air intake, intercoolers, plenum, will all adjust with the tune. If you add higher octane fuel, the ecu will adjust accordingly. Anytime you add higher octane, the fuel will burn slower providing your vehicle with improved performance. We never recommend using leaded gas such as c16 as this will destroy your o2 sensors and catalytic converters. Further custom tuning is available with provided dyno sheets or datalogging.
