So I still haven't committed to what I want for a tune. I have a superchip which I can def tell gives me power but it sounds like from what I have read it is a low point in tunes. I see everyone always recommends getting efi. Do u completely do ur own tunes with that? What exactly do you get or get to do with it? Sorry if this is a dumb question. I just can't seem to get all my answered out in the search bar.
