Performance Calibration: Mercedes Benz G63 AMG (W463)
Engine: M157 5.5L V8 Biturbo | Model Years: 2012–2018
The G63 is a global icon of power and presence. Under the hood, the M157 biturbo engine provides immense torque, yet it is significantly detuned from the factory compared to its sedan counterparts. Our calibrations transform the G-Wagon’s acceleration, providing a massive surge of power while maintaining the rugged reliability and factory safety protocols required for this platform.

🛠️ Calibration Enhancements
Our ECU software modifies over 500 parameters to provide a seamless "factory-plus" experience:
Massive Torque Gains: We focus on the M157's low-end and mid-range "shove," making the heavy G-Class feel significantly lighter and more responsive.
Optimized Boost Control: Increased boost pressure targets and wastegate duty cycle adjustments for maximum efficiency.
Drive-ability: The calibration is designed to be smooth and predictable for city driving, with an aggressive transformation when you demand full power.
Safety Fail-Safes: All factory engine protection logic remains active, including knock detection and thermal management protocols.
🔧 Recommended Maintenance
To safely support these high-output levels on the M157 platform, we recommend:
Spark Plugs: Upgrade to NGK 97506 "Step 1 Colder" plugs, gapped to 0.022".
Fuel Grade: Strictly 93 Octane (98 RON) is required for advertised performance figures.
Service Intervals: We recommend oil changes every 5,000 miles using high-quality synthetic oil (MB 229.5).
