Overview
Mercedes’ M256 inline six is a smooth and rewarding platform because the turbocharged mild hybrid setup responds well to torque target, boost and airflow calibration changes. Newer cars use locked Bosch MG1CP002 management, so the initial workflow generally starts with a bench unlock before repeat flashing is possible. Stage 2 with intake and exhaust support widens the torque plateau and gives these heavier chassis much stronger real world acceleration.
Key Features
- Luxury SUV daily gains
- smooth inline six
- bench unlock workflow
