How ECU remapping works on a petrol Seat Leon

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, TSI and TFSI are the Volkswagen Group names for its turbocharged direct-injection petrol engines.
