The Jeep Grand Cherokee 4.7 V8 230hp is a 4.7L naturally aspirated petrol engine producing 230 BHP and 400 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 250 BHP and 420 Nm — a gain of around 20 BHP (9%) and 20 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.
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.
