Don't know why he JWT 0-60 so bad.
However, they said the "JWT felt the fastest, The Vortech doesn't feel as fast but put down the best numbers. "

I still feel though that a supercharger is FAR less maitenence and can provide similiar gains, on a stock bottom end.

What I'm wondering is if this more free flowing exhaust will actually HURT my boost or my performance? Should I expect the 8lb pulley to produce 8lbs of boost with these mods? Originally I thought that these mods would help me create MORE hp/tq at lower boost levels, so that when I was boosting at 8psi, I would get another 20rwhp or so. After reading many threads I'm confused as to what the affect of having all of these mods on will be. Will my boost be at 8psi and my hp/tq be higher than a Vortec on a stock G or will my boost be at say 6.8 psi and my hp/tq be equivalent to a Vortec on a stock G?
Any advice would be appreciated.
