There is something wrong with the car. What you describe is not the way the vette works when you are in track mode. I've been at the track three times this year with my Z51. I drive in the second track setting. As I come out of the corner, even if I give it a bit too much gas the car just cuts the power just a little. You can still be going a little sideways, and have power. Your dealer doesn't understand the car.
