I have a 2013 Grand Sport. I've looked in the owners manual, I've read online posts. Can anyone please explain to me how to use this feature? For some reason when I turn the TC button to stabilitrack mode, push the clutch in and shift into first, and then floor it, it jumps to 4500 RPM instead of the preset range. And then it just roasts the tires (very expensive tires) when I dump the clutch. Anyone have any info on this? Thanks.
