Assessment
The Seat Leon 1.9 TDI 150hp is a 1.9L turbocharged diesel engine producing 150 BHP and 320 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 190 BHP and 410 Nm — a gain of around 40 BHP (27%) and 90 Nm (28%).
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 high, based on the percentage gain available from the factory output.
Considerations: High tuned torque: check transmission torque capacity and service history.. 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.
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.
