Fabspeed XperTune ECU Service for Audi S8 V10 (2006–2010)

Send the original S8 5.2-liter V10 ECU for a calibration matched to its current hardware. This bench service returns your programmed controller; the resonator X-pipe used in published tests is a separate component. 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.
