Diesel Audi A6: what changes with a remap
On a diesel the ECU decides how much fuel is injected and how hard the turbo works. A remap adjusts those calibrations within safe limits, so the gains show up mainly as extra torque low in the rev range and smoother, more responsive pull.
For reference, TSI and TFSI are the Volkswagen Group names for its turbocharged direct-injection petrol engines.
