Assessment

The Porsche Cayman GTS 3.4i 340hp is a 3.4L naturally aspirated petrol engine producing 340 BHP and 380 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 355 BHP and 400 Nm — a gain of around 15 BHP (4%) and 20 Nm (5%).

This engine has limited 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: Naturally aspirated engine: gains are usually limited; results vary widely.

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.
