My Cummins performance guy recommends EFI-Live. The '07 I bought had a Bully Dog Triple Dog Power Pup (dang, that's a mouthful!) in it when I bought it, and so far, I've not seen any glaring reason to upgrade ... yet, that is! I'm sure the itch is coming soon enough. :)

Have had the same on my 07 since new. Truck came with it.
It ain't a Smarty or EFI, but it'll black out an intersection and then SCOOT!
