Diesel Peugeot 406: what changes with a remap
Nothing is bolted on in a diesel remap. The ECU's stored maps for injection quantity, rail pressure and turbo boost are rewritten within safe limits, and because diesels make power through torque, that is where the improvement is most obvious.
For reference, HDi is the PSA name for its high-pressure common-rail diesel engines.
