The Land Rover Defender P525 (5.0) 525hp is a 5.0L naturally aspirated petrol engine producing 525 BHP and 650 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 545 BHP and 690 Nm — a gain of around 20 BHP (4%) and 40 Nm (6%).
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.
From a technical perspective, the transmission is many variants use zf 8-speed automatic (where fitted). at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. High tuned torque: check transmission torque capacity and service history.
