Fabspeed XperTune for Porsche 958.2 Cayenne Turbo / Turbo S (2015–2018)

Match the facelift Cayenne Turbo or Turbo S 4.8-liter V8 to its handheld calibration. Their different original output levels require separate files and make advertised final-output figures configuration-specific. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.
