Good Morning Sir!
Nothing beats good custom tunes that are written for you and your truck.
This is why the gryphon exist. Yes it has canned tunes(Bill's versions) like the edge but has the ability to get custom tunes loaded into it.
As of right now and the info that I have there have no significant changes to edge's canned tunes and thats what the cs+cts would come with.
Soon PHP will incorperate those 2 models into their line up as gryphons but Bill is waiting for edge's blessings.
Some of the upgraded features of those models are:
Color screens
Cts has a touch screen
Display can now use images instead of bit maps.
A couple of more user adjustable parameters.
The list goes on.....
If you'd like to read more Corey has written up some great descriptions in their respectful sub forums.
Thanks for reading my spiel and have a Great Day!
Peace
