Default will custom tunes need to be changed after 4.56's
I've got a Gryphon now with PHP perforamce and tow custom tunes. In May ill be lifting my truck ad a short time after will be putting 35's on it. When i get the tires I also plan on put 4.56's in my truck. Does anythin i my custom tunes need to be change or should they be ok? Im running 33's now and thats what was on when i ordered the custom tunes FYI.
