Is it true that only Cobb dealers can custom tune with the accessport? I just had a shop tell me that. Maybe I missed that information when I bought mine, but I would have went another route if I had known. Any way for a non dealer to tune my car?
Has anyone installed theirs without using a battery charger?
After installing, do the different drive modes (normal, sport, track) do anything? Or is it the same tune/map for all modes?
