How engine tuning works on a petrol Citroen C4

Factory petrol calibrations leave margin for poor fuel and hot climates. A remap tunes the ignition, fuelling and boost maps to make better use of that margin, which shows up as livelier throttle response and stronger acceleration.

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