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

When it comes to Turbo Porsche s, there is nothing else that can give you as much power and performance as the ECU flash. The Cayenne Turbo S is no different than the 911. It has so much uncracked potential that the ECU flash lets out making the 2008 - 2010 Cayenne Turbo S a thrill to drive. The new DFI 4.8L engine is much more equipped over the previous 4.5L. With stock 550hp at the crank, calibrating the ECU gives the Cayenne Turbo another 50 horsepower to the crank. With a gain of almost 50ft/lbs of torque, towing your other toys is like they are not even there. Because of the increased boost and horsepower, it is recommended to change your spark plugs to a 1 step colder plug if you have more that 10000 miles on yours. We also recommend upgrading your Diverter Valves with the Agency Power ones. Expect to see boost increases to about 16psi in standard and 18psi in sport mode.

Crank Horsepower Ratings:

• Stock Power 500HP | 516ft/lbs
• Tuned Power 575HP | 605ft/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.
