Our customer Dan hooked up his beautiful Porsche Cayenne Turbo with our ECU flash tune. All done via the OBDII port, it was the perfect addition to his 450HP SUV along with some secondary cat delete pipes. Already growling, the Cayenne 4.5L is now grunting with the extra boost and power from the flash. The flash increases horsepower from 450 to 495 and the torque from 457ft/lbs to 543ft/lbs.
