Not much of an update but I am currently setting up a Ram Truck for a rep with a mopar cai and exhaust. We got talking and he said that he has a friend in detroit sending him a "performance pcm". It is going to be a product that customers can purchase through mopar. The part number is not avaliable yet but that he has it being sent for his 2012 longhorn. I don't have any more info regarding this but thought I would share.
