I've never rrbheard of that I'll have to look into it. So what happens if you spin at the line?

If you spin the tires it will effect the et more if you shift by rpm than it will if you shift by time. If you got to the big buck races and look in the cars. 95% of them shift by time. My AMX is defiantly more consistent shifting on time.
