VR Tuned ECU Flash Tune Porsche Cayenne 958 S 4.8L V8 400hp 11-14

The 4.8L V8 in the Cayenne S is enough to get that vehicle moving and with style. Coming from the factory with 400HP, 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:

• Tuned Power 420HP | 392ft/lbs

How to Flash Your ECU?

• Use the DimSport handheld device. This REQUIRES a Windows PC.  You can flash between the stock and tuned at anytime. See Instructions Here.
• Bring your vehicle to our facility where we can use our Master Tool to flash your vehicle via the OBDII port.
• We can bench flash the ECU as long it is a SDI6 or SDI7 ECU. Some later model 2013 switched to SDI8 which cannot be bench flashed. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then ship it back to you for reinstallation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection. See ECU removal instructions here.

For reference, this ECU is a Siemens SDI8.
