Assessment
The Mercedes-Benz GLA 45 AMG 381hp is a 2.0L naturally aspirated petrol engine producing 381 BHP and 475 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 420 BHP and 540 Nm — a gain of around 39 BHP (10%) and 65 Nm (14%).
This engine has limited 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 moderate, 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.
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.
