I finally got the money up for a programmer and a new option is thrown in my lap with a timeframe so I want to make sure im getting the right thing. I have been saving up for the beans 6 pos so that I could shift on the fly. But I just found out that summit has the edge CTS on sale right now for 550 shipped. Having the edge would save me from having to buy gauges, but I have read on this site that the beans and customs tunes would be best for performance. Which should I buy? customs tunes then need gauges? or edge cts and it is gauges? I have an intake and exhaust but thats about as far as im gonna go. Maybe down the line doing the HPOP and intercooler off the newer 7.3 so with these little mods, do i really need custom tunes? any help or input would be awesome guys.
