Porsche Cayenne Turbo 4.5L V8 04-06 VRTuned.com August 19, 2009 Product Info Porsche Cayenne Turbo 4.5L V8 The Porsche Cayenne Turbo has a powerful 4.5L V8 engine. Stock, the car makes 450hp to the crank. But when you are in a Cayenne Turbo, it is like being in a 911. The turbos on the Cayenne can definitely take some more juice and that is just want VRTuned has done. VRTuned has engineered one of the best ECU maps for the Cayenne Turbo to give you another 58 horsepower to the crank and 57ft/lbs of torque. Turbo Stock Power – 415HP and 413ft/lbs Tuned Power – 495HP and 543ft/lbs Turbo S Stock Power – 521HP and 531ft/lbs Tuned Power – 563HP and 565ft/lbs The 04-06 Porsche Cayenne is one of the only vehicles that requires the removal of the ECU from the car. Because of the ECU communication, OBDII flashing is not available. Once the ECU is removed from the car, you can overnight it directly to VRTuned where it will be bench flashed. The ECU flash will alter your boost, fuel, and timing maps to give you a very dominating increase of power over stock. For those worried about check engine lights, there are none! Once the car is flashed, the low end torque and throttle response will be much improved. Turbos will spool quicker and the flash will have the Cayenne pulling hard to redline. The overall improvement of drivability makes the Cayenne Turbo even more fun then it was originally. VRTuned can program your vehicle no matter what country you are from or what octane you use. When modifying the Cayenne Turbo, the car only improves when adding a high flow exhaust system, air filters, and replacing the OEM diverter valves. We have different maps for those running 91 octane or 93 octane and higher. If you have any questions about the Porsche Cayenne Turbo ECU Flash, please contact us using our Support Page.
