Volkswagen Touareg 2.5 TDI 163hp Remap

The Volkswagen Touareg 2.5 TDI 163hp is a 2.5L turbocharged diesel engine producing 163 BHP and 400 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 204 BHP and 480 Nm — a gain of around 41 BHP (25%) and 80 Nm (20%).

This engine scores highly for 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 high, based on the percentage gain available from the factory output.

From a technical perspective, the ECU is a Bosch EDC16 (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.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

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.
