Fabspeed Porsche 955 Cayenne S Fabspeed XperTune Performance Software (2002-2007)

Achieve maximum power from the Porsche Cayenne S 4.5L V8 engine without sacrificing drivability or reliability by optimizing the engine's performance. Fabspeed Motorsport offers an alternative tuning method for vehicles equipped with ECU's that traditionally required bench flashing. No longer do you need to remove your ECU and mail it in for a tune. The Handheld device interfaces with the OBD-II port on your vehicle and your computer to complete the tuning process. Simply flash your Cayenne S with a Fabspeed ECU Tune utilizing the included handheld tuner. Performance ECU software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).

No need to send your ECU in to return to stock - simply use the Handheld to flash back, then to your Fabspeed XperTune again at any point!
