Assessment
The Volkswagen Touareg 4.0 V8 TDI 422hp is a 4.0L turbocharged diesel engine producing 422 BHP and 900 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 480 BHP and 1000 Nm — a gain of around 58 BHP (14%) and 100 Nm (11%).
This engine has moderate remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. 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.
