Description

The Weistec Engineering M133 ECU Tune is a performance upgrade module specifically engineered for the M133 engine found in Mercedes-Benz AMG vehicles like the A45, CLA45, and GLA45. This ECU tune delivers a substantial performance boost, with a claimed power gain of up to +64 HP. By optimizing the engine's software, it enhances throttle response and overall power delivery for a more exhilarating driving experience. Installation of this calibration requires specific considerations. The product is intended for "Stock Vehicle" use, and as noted in the calibration request form, the vehicle should be otherwise unmodified. Deviations may require a "Race Vehicle" calibration. Specific fitment details and potential hardware prerequisites for optimal performance should be confirmed with Weistec Engineering or authorized dealers.
