I am presently running EVO's Stage IV software , and k-24 turbo's. I am contemplating upgrading to the GT- stage IV, (640hp). (Garett turbo's)

My question is,1. will Todd(EVO), credit me for my previous set-up. 2. Will i be beyond the stock fuel systems limitations, while still maintaining safe A/F ratio's 3. Which clutch upgrade is prefered with this upgrade (stage 1, or stage 2)4. I have a set of S-CAR-GO long headers, which i recently removed from the car, opted to go back to stock headers, (big improvement in performance), i was thinking of purchasing thier aluminum intake system- do you recomend or not.




P.S- does anyone have 1/4 mile #'s on the standard Stage IV , vs. the GT stage IV

Thanks for any input!
