A little while back me and my roommate did some racing. He has an 02 WS6 with qtp long tubes, no cats, slp lm1 cat-back, slp air lid, and gears. We did prob about 10 runs. I would beat him top-end, especially if we did a second gear roll. He usually always has me in first by maybe half a car into second. I won about half the time and he won the other half. I thought this was strange as to how my car was nearly stock (only had intake, plugs, and flowmaster mufflers) at the time. I figured he would have pulled me pretty bad, but he never did at all. We are both pretty decent drivers as well. Input anyone??
