Assessment
The Jaguar XJ R575 5.0 V8 Supercharged 575hp is a 5.0L supercharged petrol engine producing 575 BHP and 700 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 600 BHP and 750 Nm — a gain of around 25 BHP (4%) and 50 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.
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: High tuned torque: check transmission torque capacity and service history.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
