This engine scores highly for remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
Considerations: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
