Assessment
The Porsche 911 3.8i GTS 430hp is a 3.8L naturally aspirated petrol engine producing 430 BHP and 440 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 450 BHP and 460 Nm — a gain of around 20 BHP (5%) and 20 Nm (5%).
This engine has low 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.. High tuned torque: check transmission torque capacity and service history.
