But I need guidence, I am going into to many different directions. So I need someone to slap me straight. I already have jlt cai & xcal2 from brenspeed. So I was thinking 4.10's, or maybe o/r x. How about some pulleys? What kinda gains if any on these? I had done them on my 01 gt and never really felt that much of a difference. Anything else I may be missing? I am trying to stay away from apperance for right now, because I want my car pretty much (or atleast near) complete motor wise before I start attracting attention to myself. Lets hear what you got to say.
