Is the extra money worth it for a custom dyno tune, or will a SCT be just as good. Im not sure that i want to fork over that much just for a tune right now. I figured that i would wait and do gears and tune at the same time, but i will not get gears for a few more months. Right now i have a AEM intake, Accufab 75 mm throttle body and plenum, weld in 40's, and a bassani catted x. I want to make sure that my car isn't running lean. I would need more than this for it to be running to lean correct? Thanks.
