2014 - 2017 Mercedes Benz S63 AMG - M157 V8 Bi-turbo 5.5 - Performance ECU Tuning
Performance M157 ECU tune for Mercedes Benz S63 AMG C217 with M157 5.5L V8 Bi-Turbo Engine with MED17.7.1/MED17.7.3 ECU.
Stage 1 M157 S63 AMG Performance Tune gains:
-
- 122WHP @ 4000RPM
- 193WTQ @ 2700RPM
Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance maps and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place. Factory emissions remain functional and are not disabled. Gains can vary on vehicle condition and location. AMG S and Performance models may have smaller gains due to high HP output from factory, but should results in the same HP/TQ output as base AMG models after being tuned.
