The AMG GT63 S 4-Door Coupe is one of the most complete performance sedans ever built, featuring the V8 Biturbo / twin-turbo V8 M178 engine and AWD / 4MATIC+ drivetrain. With the right ECU tuning / software upgrade, it becomes something entirely different, and unlock power upgrade, torque upgrade, sharper acceleration, and higher top speed potential.
Our Stage 1+ upgrade transforms the car’s features without compromising the refinement and balance that make this model so special.
Dyno-Proven Output
After a full calibration process involving ECU, transmission tuning (TCU), and CPC, the GT63 S now produces:
~733 hp
1030 Nm of torque
The power is deliberately limited to remain safe on low-octane fuel, ensuring reliability for professional tuning and real-world UAE driving conditions.
Refined Where It Matters
Every parameter was optimized to deliver smoother, more predictable performance:
- A flatter, cleaner torque curve
- Noticeably stronger mid-range pull
- Sharper and more immediate throttle response
All results were measured and validated through dyno testing on the DEIZ DYNO, then refined through multiple road sessions in collaboration with Morendi, completing a full chip tuning.
