How remapping works on a petrol Citroen C4

Petrol engines are remapped by refining fuelling, ignition timing and, on turbocharged engines, boost control. Done carefully this releases performance the manufacturer left in reserve, giving sharper throttle response and a stronger top end.

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