i have a 07 with the edge programer on it when i am on stage 3 and at speeds around 55 or 65 and you hold it at that speed the truck startes jerking like is loosing power give it gas or let off get off of 55 or 65 and it stops.

 

Have you upgraded the firmware? I've read there were problems with earlier versions of the firmware causing similar symptoms. I'd give that a go.
