Yeah, that second run looked a lot better. I would have thought the 2nd gear pull would have been better than the 3rd gear run. We're you spinning on the first run?
E85 will definantly help with those pesky procharged 5th gens
I'm pretty sure that sound was a waste gate + small pulley. (becoming more popular on centris ) I raced a ss with a vortech setup that sounded just like that! I wouldn't feel too bad man nice run!
