Unlock the full performance potential of your 2013-2019 Mercedes-Benz GLA45 AMG with the German Car Accessories Performance ECU Tune. Developed by German Car Accessories (GCA) under our GCA Performance line, this precision ECU calibration is specifically engineered for the 2.0L Twin-Scroll Turbo M133 Inline-4, delivering significant gains in horsepower, torque, throttle response, and overall drivability.
Engineered with a performance-first mindset, this ECU tune completely transforms the way your GLA45 AMG performs. Turbo spool is faster, throttle response becomes sharper, and power delivery is stronger throughout the entire RPM range. Whether you're carving through corners, accelerating onto the highway, or enjoying spirited weekend drives, your AMG will feel noticeably quicker, smoother, and more responsive.
Every GCA Performance ECU Tune is custom-calibrated to your vehicle and fuel quality, ensuring maximum performance while maintaining factory reliability. Both Stage 1 and Stage 2 calibrations are available. Stage 1 is designed for vehicles equipped with factory downpipes, while Stage 2 is optimized for vehicles fitted with GCA Performance Downpipes. There is no additional charge for Stage 2 tuning.
Additional tuning features include factory speed limiter removal, configurable cold start operation, adjustable exhaust burble settings, and check engine light suppression for compatible off-road downpipe applications. Before tuning begins, your factory ECU file is securely backed up, allowing your vehicle to be restored to its original software whenever desired.
Following your purchase, German Car Accessories provides the required programming cable and comprehensive installation instructions, allowing you to flash your ECU safely and conveniently from home.
Every GCA Performance ECU Tune is backed by a 1-Year Warranty.
