The Chevrolet Avalanche 8.1 V8 340hp is a 8.1L naturally aspirated petrol engine producing 340 BHP and 606 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 360 BHP and 640 Nm — a gain of around 20 BHP (6%) and 34 Nm (6%).
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.
