Vehicle-specific tuning figures vary by ECU, software version, gearbox and hardware. RemapIQ verifies the exact vehicle before programming.
The C220d is a strong candidate for a conservative Stage 1 tune because the car already offers good refinement and economy. The remap is aimed at making the car easier to drive and less dependent on downshifts when accelerating normally.

What changes with Stage 1?
We improve mid-range torque and throttle response while keeping the car comfortable and predictable. That suits the C-Class well because it is usually used as a daily driver or long-distance commuter.
Expected power and torque
Typical gains are 205–225 bhp and 450–500 Nm, though the exact result depends on the ECU version and the health of the car.
What we check first
We look at battery health, DPF status, fault memory and any evidence of boost or EGR issues.
Known vehicle-specific considerations
- The 2.0 diesel is usually very tunable if maintained properly.
- Automatic gearbox support depends on the exact transmission and software.
- A tidy service history is important on modern Mercedes diesels.
