Description
Fabspeed’s XperTune for the D3 Audi S8 optimizes the 5.2L V10 ECU for maximum power and crisp drivability without compromising reliability, validated on the company’s in-house Dynojet. Maps are available for stock cars and for builds with upgrades like Fabspeed exhausts and intakes to match the vehicle’s configuration.
