What Stage 1 involves

Stage 1 is for a standard car with nothing fitted. We read the original file off the ECU, write a calibration developed for the 15.2 DPF 441hp (324kW) 2102Nm, then road or rolling road test it before handing the car back. Nothing is added and nothing is removed, so it looks and services exactly as it did.

It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy 15.2 DPF 441hp (324kW) 2102Nm, and we check the car over before writing to it.

See the full 15.2 DPF 441hp (324kW) 2102Nm page for every file and figure, the other engines on this C15, or all Caterpillar remapping.
