VR Tuned ECU Flash Tune Porsche Cayenne 955 Turbo 4.5L V8 03-07

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 is no different than the 911. It has so much uncracked potential that the ECU flash lets out making the first generation Cayenne Turbo a thrill to drive. The 4.5L V8 engine is much more equipped once flashed. With a gain of almost 90ft/lbs of torque, towing your other toys is like they are not even there. Furthering the performance of the Turbo truck is easily done by adding race pipes or an exhaust system. 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 to have upgraded diverter valves like those from Agency Power. Expect to see boost increases to about 15psi.

Crank Horsepower Ratings:

• Stock Power 450HP | 457ft/lbs
• Tuned Power 501HP | 516ft/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.
