Main thing that I changed was the throttle boost. I run the 87 tune because it's mellow yet strong. I ran the diablo tune/93 octane tune and I burned the tires at will. Sometimes by accident, which isn't a good thing with highway patrol around. The only reason I spun so easy is because I have a open diff, but if you have a lsd then run the diablo tune with throttle boost set at what your comfortable with. I never messed with the idle settings or too much else.
