Mini Cooper S 2.0T JCW 231hp (B48) Remap

The Mini Cooper S 2.0T JCW 231hp (B48) is a 2.0L turbocharged petrol engine producing 231 BHP and 320 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 290 BHP and 410 Nm — a gain of around 59 BHP (26%) 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: Turbo petrol: fuel quality and cooling can influence repeatable performance.. High tuned torque: check transmission torque capacity and service history.. 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.
