I have a friend that is most likely going to blow his truck up, but he has a stack combination of a super chip and predator, now when i was stacking my chips (which is tst pmx2 and edge ez) i know that you want one to do fuel and one to do timing. If i'm not mistaken this chips do both or similar things to some extent. really i'm just wondering if hes a retard. Can anyone explain to me if this is a good step up or if it is a bad set up. In my mind it doesn't sound good at all, but correct me if i am wrong.
