The Volkswagen Touran 1.9 TDI 105hp is a 1.9L turbocharged diesel engine producing 105 BHP and 250 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 140 BHP and 320 Nm — a gain of around 35 BHP (33%) and 70 Nm (28%).
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 typically a Bosch EDC15 (likely), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine..
Considerations: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.
Fuel economy note: possible improvement with conservative driving.
