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

Program the facelift Cayenne S or GTS through the specified handheld workflow. The calibration needs the actual 958.2 controller and fuel/hardware specification rather than an earlier Cayenne file. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
