Short answer: The AMG models A45, C63, E63, and GLC63 are factory-throttled by ECU, CPC, and TCU limits: torque limitation, VMAX restriction at 250 km/h, slow shift times. Our Stage-1 Triple Tuning releases full torque, removes VMAX, and shortens 9G-Tronic / DCT shift times — maximum performance without hardware intervention, safely calibrated with OEM protection mechanisms.
Mercedes-AMG stands for uncompromising performance – but even the most powerful models are not yet at their limit from the factory. Through professional optimization of ECU, CPC & TCU, we can unleash the full potential of your A45, C63, E63, or GLC63 AMG. 🚀
Whether it's performance enhancement, VMAX removal, or transmission optimization – at Stefanel Performance, you get custom tuning for your AMG model.
📌 Why chip tuning for AMG?
Mercedes-AMG models feature powerful engines, but the factory software contains numerous restrictions:
- 🔴 Limited power – Factory-throttled engine control
- 🔴 VMAX restriction – Electronically limited top speed
- 🔴 Restricted torque – Especially in CPC-controlled models
- 🔴 Slow shift times – Tuned for comfort from the factory
With our individual optimization, we ensure noticeably more power, more direct responsiveness, and maximum driving dynamics. 💪
🔥 What performance gains are realistic?
Our software adaptation adjusts all relevant parameters to optimize your vehicle safely and efficiently.
| Model | Stock (HP / Nm) | Stage 1 (HP / Nm) | Stage 2 (HP / Nm) |
|---|---|---|---|
| A45 S AMG (W177) | 421 HP / 500 Nm | 470 HP / 570 Nm | 500 HP / 600 Nm |
| C63 S AMG (W205) | 510 HP / 700 Nm | 580 HP / 850 Nm | 620 HP / 900 Nm |
| E63 S AMG (W213) | 612 HP / 850 Nm | 680 HP / 950 Nm | 720 HP / 1000 Nm |
| GLC63 S AMG (X253) | 510 HP / 700 Nm | 580 HP / 850 Nm | 620 HP / 900 Nm |
These values are possible without hardware modifications and already offer a huge performance increase.
