Mercedes-Benz C Class (W204) 2007> C230 201bhp remap figures

Who is the Stage 1 map for?

• Drivers who want a sharper throttle and a small, honest gain from software alone.
• Owners who would rather keep the car standard in every other way.
• Anyone who wants the fullest software-only map for this engine, accepting that the gain is modest without a turbocharger.

What this means for your C Class

Naturally aspirated petrol engines have no boost to raise, so gains from software alone are more modest than on a turbocharged car and come from fuelling, ignition and throttle response.

The ECU recorded for this variant is a Bosch ME9.7. 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.
