This engine has moderate 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 transmission is many variants use zf 8-speed automatic (where fitted); manuals also exist. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. Unusually high gain for NA engine: treat as an estimate and verify against the exact engine variant.. High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
