VR Tuned ECU Flash Tune Porsche Cayenne 958 Turbo 4.8L V8 11-13

The Porsche Cayenne Turbo 958 chassis is a monster SUV with its V8 twin turbocharged engine. There is no question on the performance output that can be had. Like all other Porsche Turbos, the Cayenne is no different with the power increase and driveability performance that can be had. As we have seen on other Porsche Turbo vehicles, we can gain anywhere from 75+ reliable horsepower with just a flash. Improving the vehicles throttle response, reducing the turbo lag, and improving the pull throughout the RPM range is all part of enhancing the vehicle with an ECU tune.

Crank Horsepower Ratings:

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 SDI6/7.
