What a remap does for a diesel Peugeot 307
Modern diesels are held back by conservative factory calibrations. A remap updates the fuel and boost maps stored in the ECU, which is why drivers notice stronger acceleration from low revs and less need to change down on hills or when loaded.
For reference, HDi is the PSA name for its high-pressure common-rail diesel engines.
