M177 CPC Tune
On modern AMG platforms, the CPC (Central Powertrain Controller) is responsible for monitoring and limiting engine torque. Even with an ECU and TCU tune, the CPC can aggressively reduce power if left untouched.
The DTK M177 CPC Tune removes these hidden torque restrictions, allowing the engine and transmission to deliver their full calibrated output safely and consistently.

Why CPC Tuning Is Required
•Eliminates factory torque caps
•Prevents power reduction under load
•Ensures ECU and TCU operate without intervention
•Provides smooth, uninterrupted power delivery
For higher-performance setups, CPC tuning is essential to achieve the expected gains and maintain reliability.

New CPC Module Included
Due to factory protection and security limitations, a new CPC module is required for tuning.
✅ A brand-new CPC module is included with our tuning kit
✅ Preconfigured and calibrated for your specific vehicle
✅ No reuse or modification of the original CPC required
This ensures a clean, reliable solution with OEM-level integration.
