Petrol Seat Altea: what changes with a remap
A petrol remap re-works the engine management calibration: air-fuel ratio, ignition advance and boost where fitted. The result is more power and a more immediate throttle, delivered by software rather than hardware changes.
For reference, TSI and TFSI are the Volkswagen Group names for its turbocharged direct-injection petrol engines.
