If you are talking about curise control. None of the V8 Crossfire's have cruise control. It is something we give up to have a V8. You probably don't want to spend that much to get rid of it.

I have to turn off the traction control to get my car to move off the line at all. If I spin the tires past 4500 rpm the traction control kicks in again even with the switch off. I haven't worried about this becuase if I need to spin the tires all the way to redline then I need to work on my launch technique. I do believe there is a fuse you can pull or a wire in the little box near the battery that will totally disable it.
