its not what you are missing, its what I am missing lol.

I dunno... im happy with the results for the most part considering the car dyno'd at 254 rwhp with an intake and tune. My buddy put down 450/368 with the same setup on the same dyno with 18's, Auto, 3.73's and LTs. I dont think im considerably far off of those numbers with my 20's, Auto, 3.73's, DS.
