Mercedes-AMG GLC43 Stage 1 Engine Tune

We recently carried out a bespoke Stage 1 ECU calibration on this Mercedes-AMG GLC 43, unlocking additional performance from the twin-turbocharged V6 engine while maintaining the refinement, drivability and everyday usability expected from an AMG SUV.

The Stage 1 calibration delivers a noticeable improvement throughout the rev range, with stronger mid-range torque, sharper throttle response and improved acceleration.

The additional torque helps the GLC 43 pull harder from lower RPM while providing a more urgent and responsive feel under acceleration, making overtaking and motorway driving considerably more effortless while retaining smooth power delivery for everyday use.

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

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 confirm the vehicle is operating correctly once the software installation is complete.
