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