The 2008 and up Porsche Cayenne is a nice change over the previous 955 models. The new Cayenne GTS is now direct fuel injection with a 4.8l v8 engine that is equipped for the sportier driver. With stock 405hp at the crank, tuning the GTS allows for another
15 horsepower and 20ft/lbs of torque to the crank. The biggest difference when you flash the 957 Cayenne GTS is the overall improvement of the power curve. The truck has much better throttle response and improved torque for those times you need to haul some other toys. The newly flashed truck picks up right away and pulls harder through the mid and top end rpm range. Overall, the daily driving characteristics are vastly improved while providing you additional benefits that the Porsche craves.
Crank horsepower ratings:
Stock power 405hp and 369ft/lbs
Tuned power 420hp and 390ft/lbs

With the vr tuned ecu flash, basic bolt-on performance parts will not require a retune of your ecu. Adding parts such as an exhaust, headers, air intake, throttlebody and plenum, will all adjust with the tune. Raising the secondary o2 limits for cat delete or high flow cats as well as raising the rev limiter is available upon request. If you add higher octane fuel, the ecu will adjust accordingly. Anytime you add higher octane, the fuel will burn slower providing your vehicle with improved performance. We never recommend using leaded gas such as c16 as this will destroy your o2 sensors and catalytic converters. Further custom tuning is available with provided dyno sheets or datalogging.
