How engine tuning works on a petrol Audi A8

Petrol engines are remapped by refining fuelling, ignition timing and, on turbocharged engines, boost control. Done carefully this releases performance the manufacturer left in reserve, giving sharper throttle response and a stronger top end.

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