Suzuki Vitara 1.4 Boosterjet 140hp Remap

The Suzuki Vitara 1.4 Boosterjet 140hp is a 1.4L naturally aspirated petrol engine producing 140 BHP and 220 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 170 BHP and 280 Nm — a gain of around 30 BHP (21%) and 60 Nm (27%).

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: Naturally aspirated engine: gains are usually limited; results vary widely.. Unusually high gain for NA engine: treat as an estimate and verify against the exact engine variant.. 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.
