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.
