Diesel Mercedes ML-class: what changes with a remap

On a diesel the ECU decides how much fuel is injected and how hard the turbo works. A remap adjusts those calibrations within safe limits, so the gains show up mainly as extra torque low in the rev range and smoother, more responsive pull.

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