This is an extreme Stage 3 performance calibration for the Mercedes-Benz A45 AMG (W176 Facelift), equipped with the Bosch MED17.7 ECU. This tune is designed exclusively for highly modified vehicles and is intended for dedicated track or competition use. It goes far beyond a typical remap, re-engineering the engine's parameters to work with extensive hardware upgrades.
To use this file, your vehicle MUST be equipped with supporting modifications, including at a minimum: an upgraded or hybrid turbocharger, a high-flow downpipe (decat), an upgraded intercooler, and often an upgraded fuel system. This software unlocks the maximum possible performance from the 2.0L AMG engine, delivering brutal acceleration and a powerband optimized for the racetrack.
