Unlock the hidden performance of your 2016-2023 Mercedes-Benz E200, E250, or E300 with the GCA Performance ECU Tune. Developed in-house by German Car Accessories (GCA), this ECU calibration is engineered to maximize the performance potential of the 2.0L Turbocharged M274 and M264 engines while maintaining excellent drivability and reliability.
Our custom ECU tune sharpens throttle response, increases horsepower and torque throughout the powerband, and delivers smoother, more consistent acceleration. Whether you're commuting daily or enjoying spirited driving, you'll experience stronger mid-range power, improved responsiveness, and a noticeably more engaging driving experience.
Each tune is calibrated specifically for your vehicle and fuel quality while safely retaining factory drivability. GCA Performance securely saves your original ECU software, allowing you to revert your vehicle back to stock at any time.
For vehicles equipped with aftermarket downpipes, Stage 2 tuning is available at no additional charge and includes check engine light suppression for off-road use only.
