I own a C6 Corvette Grand Sport. When the Diablo tune is uploaded, is there any difference in the tune parameters when the driver selects 'Competition Mode' versus the standard driving mode? In the stock GM tune, I believe the Comp Mode increases the rev limiter & timing and decreases torque management parameters, possibly other parameters also. Does the InTune program apply tuning parameters to both 'Modes' or just one of the Modes (which one)?
The InTune is a great product and I highly recommend it to other C6 owners!
