Description
Discover the incredible power within your 2008-2010 Porsche Cayenne 957 Turbo S with a professional ECU flash from CT Tuning. While the factory 4.8L DFI engine is already a powerhouse, our custom calibration releases uncracked potential, delivering a surge of horsepower and torque that transforms your SUV into a high-performance thrill ride. This upgrade provides a significant boost in pull and towing capability, ensuring your Cayenne performs with the same DNA as a 911. To support the increased power and boost levels—expected to reach 16psi in standard and 18psi in sport mode—we recommend installing one-step colder spark plugs and upgraded Diverter Valves.
