Assessment

The Porsche Boxster Spyder 3.4i 320hp is a 3.4L naturally aspirated petrol engine producing 320 BHP and 360 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 338 BHP and 385 Nm — a gain of around 18 BHP (6%) and 25 Nm (7%).

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.
