Economy files show no new power figure because they are written for torque and drivability rather than peak output.

Remapping the C 350i

The Mercedes C W204 2007 to 2010 C 350i runs a factory calibration built to cope with poor fuel, skipped servicing and hot countries. We rewrite the fuelling, boost and timing for this engine on this car, then test it before you get it back. The original file is kept, so it can go back to standard whenever you want.

On the petrol side the difference shows in throttle response and in how hard it pulls through the top half of the rev range. It feels sharper off idle and keeps going where it used to flatten out.

Figures on this page are for a standard car in good health. We read the fault codes and check the basics first, and if something needs attention we will tell you before we write anything. Have a look at the other engines on the W204 2007 to 2010, the full C range, or everything we do for Mercedes.
