After hours of data acquisition and numerous runs on the dynamometer, AMR Performance has engineered and developed ECU Software upgrade(s) for the Mercedes-Benz AMG GT63/63s. Not only does this upgrade give the vehicle an increase in horsepower, torque, but also increase the turbocharger’s response, increase in boost levels, optimal fuel curve, and an increase in throttle response! This well engineered recipe turns this normally commuter vehicle into a torque filled throttle happy warrior!
Power increases are based on AMR Performance actual measured stock horsepower numbers and not those reported by Mercedes-Benz.
Reported power figures measured on AMR Performance in-house AWD Dynamomenter (dyno) are with US Spec vehicles, using standard corrections and an based on an average of multiple vehicle runs. Specific figures are estimated based on in-house measured wheel power figures and will vary. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.
