Porsche Panamera Sport Turismo 4.0T GTS 460hp Remap

The Porsche Panamera Sport Turismo 4.0T GTS 460hp is a 4.0L turbocharged petrol engine producing 460 BHP and 620 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 620 BHP and 870 Nm — a gain of around 160 BHP (35%) and 250 Nm (40%).

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.

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.
