The Porsche Cayenne turbo 958 chassis is a monster suv with its v8 twin turbocharged engine. There is no question on the performance output that can be had. Like all other Porsche turbos, the Cayenne is no different with the power increase and driveability performance that can be had. As we have seen on other Porsche turbo vehicles, we can gain anywhere from 80-115hp reliable with just a flash. Improving the vehicles throttle response, reducing the turbo lag, and improving the pull throughout the rpm range is all part of enhancing the vehicle with an ecu tune. The Cayenne turbo engine is shared with the panamera turbo which we have had the chance to tune up. We spent countless hours testing different tuning maps to get the perfect gain in performance. Our mustang awd dyno has a drivetrain loss of about 20-25% which is normal for this low reading machine. The turbo comes with 500 crank horsepower and our stock baseline is about 380 to the wheels. Tuning the cars timing and fuel maps, along with raising the boost pressure, we were able to take the car to about 460 wheel horsepower and 410 ft/lbs of torque. The suv gets a bump from 500hp to 600hp with a ecu flash. Standard mode takes boost pressure up to 1.2bar where sport and sport plus show a change to about 1.3bar. Depending on your exhaust system or other intake mods, you may see +/- 0.1bar of boost difference.



Crank horsepower ratings:

stock power 500hp and 516ft/lbs

tuned power 600hp and 550ft/lbs



Wheel horsepower ratings:

stock power 378hp and 364ft/lbs

tuned power 455hp and 409ft/lbs



Note:upon ordering of this ecu flash tune, you will be required to send in your ecu. Once we receive the ecu and program it, we will ship it back to you via the method you select at checkout. The Cayenne sdi6 ecu cannot be flashed via the obdii port. This requires the ecu to be mailed in to us to be benched flashed. Bench flashing requires the ecu to be opened. We do not solder or modify your board in any way. Using a electrical contact pins, we tie into the boards programming mode to read and write the file. We do store your stock file if you ever want to revert. Because the ecu must be removed and opened, if you are concerned with warranty, you may want to speak with your dealership. Removing the ecu takes about 20 mins and we have provided instructions linked below. 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, air intake, intercoolers, plenum, will all adjust with the tune. 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.
