This engine scores highly for 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 high, based on the percentage gain available from the factory output.

From a technical perspective, the ECU is typically a Bosch MED17 (likely), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine..

Considerations: Turbo petrol: fuel quality and cooling can influence repeatable performance.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
