Hey all, I'm getting ready to install a 2.60 pully and idler on my stock '12 gt500. I was going to order a SCT/tunes from VMP but noticed American Muscle also can tune gt500s through Bama. Does any one else have tunes from BAMA on a similar set up. The price is alot less than VMP so that's why the debate. Or is it u get what u pay for type of thing?
