Mercedes-AMG GT63 (C192) Tuning Guide — M177 V8 Performance for the GCC | YPG Motorsport
The second-generation Mercedes-AMG GT (C192) brings AMG's handcrafted M177 4.0-litre twin-turbo V8 into a sharper, more usable GT coupe. The GT63 4MATIC+ is factory-rated at 577 hp, the GT63 PRO at around 603 hp, and the GT63 S E Performance pairs the same V8 with an electric motor for roughly 805 hp as a plug-in hybrid.
M177 is core YPG Flash territory
The M177 V8 is one of the platforms YPG calibrates through YPG Flash, our remote OBD2 process. For supported GT63 models, you flash your own ECU over the OBD port using an AutoTuner tool while YPG delivers the custom calibration remotely — no shop visit, and no ECU removal. It is the same proven AMG V8 family YPG has tuned for years.
Stage 1 and Stage 2
- Stage 1 — ECU calibration on the stock GT63, raising boost within safe limits and sharpening throttle and gearbox behaviour.
- Stage 2 — calibration matched to downpipes and intake for stronger, more sustained power.
Built for GCC heat
The M177 makes its best, safest power on a calibration written for local conditions. YPG sets knock thresholds, fuelling, and thermal protection for 95 RON and up to 50°C ambient — the real Kuwait and GCC summer environment — rather than a generic European file.
