How remapping works on a diesel Audi A6

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, TDI is the Volkswagen Group name for its turbocharged direct-injection diesel engines.
