Will a Predator U7137 work on a 2012 Hemi ram ?

Bought a Perdator U7137 years ago to program my 2007 hemi ram. Drove that truck 127,000 miles with the tune and enjoyed every mile of it. Now upgraded to a 2012 Hemi ram and still have the U7137 on the shelf. Will it work for basic tuning on the 2012 ?
