How is the the Allison in learning how to adapt with the various Edge settings? Does the Edge have increased diesel chatter, present with in the Predator? Thinking of making the move to the Edge due to shift on the fly and digital read out on ***. Any sug. would be great.

tranny usually takes a few hundred shifts to adapt when switching levels,that is in the Edge/*** manual. As far as chatter..any time you add power via chip/programmer it will get louder.
You can find manuals for edge and *** here www.edgeproducts.com

btw...I removed the "help" from your title.. since this isn't any type of problem, you are just asking for info.
