VR Tuned ECU Flash Tune Porsche Cayenne 957 S 4.8L V8 DFI 08-10

The 957 Porsche Cayenne is a nice change over the previous 955 models. The new Cayenne S is now Direct Fuel Injection with a 4.8L V8 engine that is equipped for the sportier driver. With stock 385hp at the crank, tuning the S model is the same as the GTS. This allows for a huge increase in horsepower and torque. The biggest difference when you flash the Cayenne 957 S is the overall improvement of the power curve. The truck has much better throttle response and improved torque for those times you need to haul some other toys. The newly flashed truck picks up right away and pulls harder through the mid and top end RPM range. Overall, the daily driving characteristics are vastly improved while providing you additional benefits that the Porsche craves.

Crank Horsepower Ratings:

• Stock Power 385HP | 369ft/lbs
• Tuned Power 405HP | 395ft/lbs

How to Flash Your ECU?

• Use our OBDII VR Tuned iFlash Cable. This REQUIRES a Windows PC. You can flash between tuned and stock at anytime.  See Instructions Here.
• Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. 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. 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 SDI4.
