We're currently in negotiations with Edge regarding offering custom tuning for the EvoCS and EvoCTS. Everything so far is looking very positive.
As soon as we know something for sure, we'll be posting!
As far as upgrading goes, I believe that the hardware is actually different, so I'm at a loss as to how that might work. Again, as soon as we have some cold, hard facts, we'll let everyone know.
(As soon as the EvoCS and EvoCTS are released for the Fords, we'll probably make a new section for them and move this thread. Until then, this works for me!)
