What a remap does for a petrol Citroen C4
On a petrol car the ECU controls fuelling, spark timing and any turbo boost. A remap re-calibrates those maps within safe limits, so the car responds more eagerly and pulls harder through the rev range.
For reference, HDi is the PSA name for its high-pressure common-rail diesel engines.
