Unlock the full performance potential of your 2009-2011 Mercedes-Benz E63 AMG with the German Car Accessories Performance ECU Tune. Developed by German Car Accessories (GCA) under our GCA Performance line, this ECU calibration is engineered to maximize the capabilities of the legendary 6.2L naturally aspirated M156 V8, delivering sharper throttle response, stronger acceleration, and significantly improved drivability.
Rather than simply increasing peak power, GCA Performance ECU tuning optimizes the entire powerband. Throttle response becomes more immediate, torque delivery is smoother and more consistent, and the engine pulls harder from low RPM through redline. Every calibration is carefully refined to deliver a factory-quality driving experience with enhanced performance and reliability.
Each tune is tailored to your vehicle and fuel quality, with support for multiple octane ratings and both Stage 1 and Stage 2 performance configurations. Stage 1 is designed for vehicles with factory exhaust components, while Stage 2 is optimized for vehicles equipped with GCA Performance Downpipes. There is no additional charge for Stage 2 tuning.
Additional performance features include configurable cold start operation, factory speed limiter removal, enhanced exhaust burble settings, and check engine light suppression for compatible off-road downpipe applications. Your factory ECU file is securely backed up before tuning, allowing the vehicle to be restored to its original factory calibration at any time.
After purchase, German Car Accessories provides detailed tuning instructions along with the required programming cable, allowing you to flash your vehicle from home.
Every GCA Performance ECU Tune is backed by a 1-Year Warranty.
