The Edition 507 has always been one of the most iconic versions of the W204 C63 — the strongest C63 AMG factory version after the Black Series. But with a properly engineered Stage 1 ECU calibration, it becomes exactly what it should have been from the factory.

On the DEIZ Dyno, the upgraded Edition 507 delivered: +22 hp over stock +20 Nm increase in torque Faster, more immediate throttle response A stronger, more confident mid-range A cleaner and smoother pull all the way to the top end

Every run was logged and verified, ensuring dyno-tested gains during the rolling road session.

To make the 6.2L naturally aspirated M156 feel its best we carried out:

• Stage 1 ECU calibration with optimized ignition timing and fueling
• Improved drivability mapping for better pedal feel and smoother transitions
• Engine cooling system optimization, helping with the elimination of heat-soak tendencies on spirited drives

This approach refines what already sets the Edition 507 apart in the Edition 507 vs base C63 AMG comparison, highlighting why it’s the preferred platform for C63 AMG tuning.

The result is a C63 that feels lighter on its feet: quicker to react, more stable under load, and noticeably stronger through the mid-range, exactly what well-executed chip tuning Edition 507 should deliver.
