well...heres the deal...my car is all stock right now...im planning to get a greddy type-s bov recirculating, an aftermarket exhaust, an intake, and a bigger intercooler for my evo....the problem is...i heard getting exhaust and bov and intake you would need to tune your car a bit to make it run efficient....is there anything that can automatically do that for me? like what does an AFC do? do i need that? because im sure im going to be getting an intake and bov first...and i do want my car to run smoothly and no damaging to my turbo and all..so yeah...what do i need to do?
