The Chevrolet Avalanche 5.3 V8 295hp is a 5.3L naturally aspirated petrol engine producing 295 BHP and 454 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 315 BHP and 485 Nm — a gain of around 20 BHP (7%) and 31 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.
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. High tuned torque: check transmission torque capacity and service history.
