Who is the Stage 1 map for?
- Drivers who want stronger pulling power for overtaking, hills and towing, with no parts to fit.
- Daily and motorway drivers who want the engine to feel less strained at cruising speed.
- Anyone who wants the biggest software-only change we list for this engine.
What this means for your C Class
On a diesel the biggest change is normally torque: the remap changes how much fuel and boost the ECU allows across the rev range, so pulling power arrives earlier and holds on longer.
This car is listed with a Delphi CRD3 engine control unit. We read the ECU on your car and compare it with the software listed here before any work starts, so you know what to expect before you commit.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.
