Petrol Citroen C3: what changes with a remap
With a petrol engine the remap works through the ECU's ignition, fuelling and turbo boost tables. Re-calibrating them within safe limits releases power that is already there, rather than adding anything to the engine.
For reference, HDi is the PSA name for its high-pressure common-rail diesel engines.
