I'm just about to order a gryphon for my 2004 5.4L ford f-150, but im not sure about if i need to order any custom tunes at the moment. Right now the only modification that I have on my truck is i removed the stock muffler and put on a 12" glass pack (gets that little extra sound i wanted
). Would a custom tune really do anything extra at this point?
The canned tunes are tranny only, 87 tow, and 93 performance. What do most people run on as far as canned tunes go for everyday use?
