What a remap does for a diesel Mercedes ML-class

Diesel engines respond strongly to remapping because the ECU controls injection quantity, injection timing and turbo boost pressure. Re-calibrating those maps typically brings the biggest improvement in mid-range torque, which is what you feel when overtaking or towing.

For reference, CDI is the Mercedes-Benz name for its common-rail diesel engines.
