Volkswagen Jetta 1.4 TSI 140hp Remap

The Volkswagen Jetta 1.4 TSI 140hp is a 1.4L turbocharged petrol engine producing 140 BHP and 220 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 200 BHP and 300 Nm — a gain of around 60 BHP (43%) and 80 Nm (36%).

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 MED9/MED17 (varies), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine..

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.
