Renault Megane RS Trophy 1.8 Turbo 300hp Remap

The Renault Megane RS Trophy 1.8 Turbo 300hp is a 1.8L turbocharged petrol engine producing 300 BHP and 400 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 310 BHP and 440 Nm — a gain of around 10 BHP (3%) and 40 Nm (10%).

This engine has moderate remap suitability, though the available headroom is limited, so gains are modest compared to higher-output variants. The tuning headroom is classified as limited, 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.

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.
