Despite being one of the heavier cars that Mercedes produces, the twin turbo charged engine under the hood of the S63 gives the car surprising performance. With our custom Mercedes S63 AMG ECU Flash, we improve the performance of the car by altering the fuel/ignition/boost tables and increase the overall throttle response. The result is an increase of 50 peak HP and 99 peak TQ. You will notice an immediate increase in acceleration as the additional power pushes you even further back into your seat.
Our Mercedes S63 AMG ECU Flash is the simplest way to add instant power to any car without having to alter any mechanical components, and gives you the most bang for your buck.
