We recently carried out a bespoke Stage 1 ECU calibration on this Mercedes-AMG A35, unlocking additional performance from Mercedes-Benz's turbocharged 2.0 litre M260 engine while retaining the sharp drivability, refinement and everyday usability expected from an AMG performance model.

The Stage 1 calibration transforms the character of the vehicle, delivering stronger acceleration, improved responsiveness and a noticeably more engaging driving experience while maintaining OEM-like reliability and drivability.



Performance Figures

Stock: 306 hp / 400 Nm

Stage 1: 345 hp / 480 Nm

Increase: +39 hp / +80 Nm

The Stage 1 ECU calibration delivers a substantial increase in both power and torque throughout the rev range, with stronger mid-range performance, sharper throttle response and significantly improved acceleration.

The additional torque allows the vehicle to pull harder from lower RPM while improving flexibility and responsiveness in every gear. The result is an AMG that feels considerably more urgent and capable under acceleration while retaining the smooth power delivery and refinement that make the A35 such an impressive all-round performance car.

Unlike generic tuning files, our calibrations are developed to provide strong, usable performance while remaining within the safe operating limits of the engine and drivetrain.

Additional Software Options Included

As part of this vehicle's setup, we also carried out:

• Speed Limiter Removal

Dealer-Level Diagnostics Included

Every tuning appointment includes advanced dealer-level diagnostics before and after the calibration process.

This allows us to identify any underlying issues that could affect performance and confirms the vehicle is operating correctly once the software installation is complete.
