Assessment
The Audi S6 4.0 TFSI 420hp is a 4.0L turbocharged petrol engine producing 420 BHP and 550 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 540 BHP and 800 Nm — a gain of around 120 BHP (29%) and 250 Nm (45%).
This engine scores highly for remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is typically a Bosch MED17 (likely), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine. some dsg/dual-clutch gearboxes have torque management; calibration may be torque-limited. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: Turbo petrol: fuel quality and cooling can influence repeatable performance.. High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
