It's really just a question of forgetting what the other car was like and getting to know the Crossfire better. What you need to do is street race more oft.....oh, wait, that's maybe not the very best advice I've ever given

No, don't street race, it's dangerous and illegal. But really dangerous. And kinda stupid too.
Just drive the car hard from time to time until you get used to winding out 1st gear and grabbing 2nd at the right moment. I had sort of the same learning process when I replaced my Miata with the Crossfire.
Then go out and find that Camaro again.
