All you need is the Superchips model that'll work with Dodge trucks. Regardless of where you get it, the first thing you'll have to do is plug it into a computer and update it. Once updated it'll have the files for both the 2009 and the 2010. It isn't until you plug it into your truck that it'll dedicate the tuner to the vehicle.
If you buy one, don't update it, and then just plug it into the truck, it'll eventually flash on the screen that your vehicle isn't supported.
