The Seat Leon 1.8T 20v 225hp is a 1.8L turbocharged petrol engine producing 225 BHP and 280 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 260 BHP and 400 Nm — a gain of around 35 BHP (16%) and 120 Nm (43%).
This engine scores highly for 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 high, based on the percentage gain available from the factory output.
Considerations: Turbo petrol: fuel quality and cooling can influence repeatable performance.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
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.
