Yea I know I need some PI heads but once again buying them is one thing then its gonna cost a lot to have them installed
just like my headers, got them for cheap and its gonna cost alot to have them installed. I've been asking around hoping to find a friend with a hook-up to do my headers like 100 bucks or somethin I'd do but the PI heads would be alot to have installed I just know it. Funny thing though, had my stang for more then a year now and have still never seen 4500 or above anyhow hehe been to 4000 I think but never really put the pedal to the floor yet I will when I do my g-tech test like 0-60 and 1\4, thanks for the input. I guess I'll hold off on the 70 but still put the plenum on.
