This is an extreme performance package for the Mercedes-Benz A45 AMG, featuring a "Stage 2 Hard" calibration for the Bosch MED17.7 ECU. This package is designed for highly modified vehicles and is intended for track and competition use, requiring an upgraded high-flow or decat downpipe for correct operation.
The package includes two modified files for maximum flexibility. The first is a pure Stage 2 Hard tune, focused on delivering the most aggressive power and torque gains. The second file includes the same powerful Stage 2 Hard calibration, plus the activation of a loud Pop & Bang (overrun burble) feature and deactivation of the Start/Stop system for enthusiast convenience. This is the ultimate software solution for a track-ready A45 AMG.
