FabSpeed Audi S8 V10 ExperTune Performance Software

Achieve maximum power gains and driveability without sacrificing reliability. Maps are available for completely stock cars, or for cars equipped with an upgraded exhaust, intake or other performance enhancements. Increase the power and driveability by optimizing the ECU. We've had ample time with the 5.2L V10 S8 on our in-house Dynojet to unlock extra power on both stock vehicles and optimize performance with a Fabspeed exhaust. Once we receive your ECU, our tuner bench flashes it with the upgraded ECU map and we return it to you for easy re-installation; no modifications to the vehicle are necessary.   COMPATIBILITY Fits all Audi S8 5.2L V10 vehicles (2006-2010) POWER GAINS  The dyno chart is a comparison between a stock S8 V10, followed by the addition of our Resonator Bypass X-Pipe and Fabspeed ECU Tune. All testing was done on our in-house Dynojet by our experienced tuner. Stock = 312 whp / 298 ft-lbs ECU Tune + Fabspeed Resonator Bypass X-Pipe = 341 whp / 340 ft-lbs Peak
