The Maserati Quattroporte 4.2 V8 400hp is a 4.2L naturally aspirated petrol engine producing 400 BHP and 460 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 425 BHP and 485 Nm — a gain of around 25 BHP (6%) and 25 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.. High tuned torque: check transmission torque capacity and service history.
