ive heard alot of different do's and donts about this setup... but i was wondering if you guys think i should do the fast 90/90 or 92/92. with that and a retune do you think i could make a good amount of extra power? ive got an ls6 intake and stock throttle body. i would LOVE if i put the combo on and with a retune make 450rwhp.. sorry forgot my sig. i make 420rwhp right now
