What a remap does for a diesel Peugeot 406

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, HDi is the PSA name for its high-pressure common-rail diesel engines.
