Performance Calibration: Mercedes-AMG G63 (W463A)

Engine: M177 4.0L V8 Biturbo | Model Years: 2019+

The M177 in the current-generation G63 is a masterpiece of modern engineering. While it delivers staggering power from the factory, the engine hardware is shared with AMG's supercar lineup, leaving immense room for software optimization. Our calibrations sharpen the 9-speed shifts and unlock a level of torque that transforms this 5,800lb icon into a high-performance athlete.

🛠️ Calibration Enhancements

Hot-V Turbo Optimization: We optimize the boost curves for the twin-scroll turbos to provide instantaneous "tip-in" response and a massive mid-range surge.
Transmission Mapping: Torque reporting to the 9-speed TCT is recalibrated to ensure the gearbox manages the increased output with faster, crisper shifts.
Refined Drivability: Comfort mode remains docile and smooth for luxury cruising, while Sport+ and Sand/Rock modes receive sharpened throttle mapping.
Safety Protocols: All factory fail-safes—including knock detection, oil temperature limits, and cylinder deactivation logic—remain 100% operational.

⚡ Critical Note: 2019+ CPC Module

All 2019 and newer G63 models are equipped with a CPC (Central Powertrain Controller).

While our ECU calibration provides a significant boost, the CPC module contains secondary torque limiters and top-speed governors.
For Stage 2 builds looking to achieve maximum torque and speed, a CPC Bypass or Re-calibration is highly recommended to unlock the vehicle's full potential.

🔧 Recommended Maintenance

Spark Plugs: For Stage 1 and 2, we recommend upgrading to NGK 97506 (Step 1 Colder) gapped to 0.022".
Fuel: Strictly 93 Octane (98 RON) is required for advertised gains.
Oil Service: Reduce intervals to every 5,000 miles using high-quality synthetic (MB 229.51/229.52).
