Assessment
The Holden Commodore 5.7 V8 306hp is a 5.7L naturally aspirated petrol engine producing 306 BHP and 460 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 340 BHP and 500 Nm — a gain of around 34 BHP (11%) and 40 Nm (9%).
This engine has limited remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. 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.
