Assessment
The Audi A8 4.2 TDI 350hp is a 4.2L turbocharged diesel engine producing 350 BHP and 800 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 400 BHP and 950 Nm — a gain of around 50 BHP (14%) and 150 Nm (19%).
This engine has moderate 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 moderate, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is a Bosch EDC17 (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: High tuned torque: check transmission torque capacity and service history.
Fuel economy note: possible improvement with conservative driving.
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.
