The McLaren Senna 4.0 V8 800hp is a 4.0L naturally aspirated petrol engine producing 800 BHP and 800 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 850 BHP and 900 Nm — a gain of around 50 BHP (6%) and 100 Nm (12%).
This engine has limited remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. 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.
