OperATION
Engine Tuning:
During the download the GT will prompt all gasoline users to select the desired engine tune.
At this point simply specify the engine tune; the table below illustrates the three settings
available: Premium, Regular, and Stock. Diesel users do not have to select an engine tune,
the diesel GT automatically loads the tuning information into the vehicle.
