I strongly recommend an OEM Cummins programmer.
Funny guy. . I personally like the Smarty.
Lot's of TDR members agree with your choice.
Every once in a while one of them is here whining because their engine or transmission is trashed and Dodge won't honor their (voided) warranty.
Each to his own. You are your own warranty station.
Love my smarty. I am now running it on sw2, tq 4, timing 2, rp 2, vgt 4, with power puck 100% and am getting 17 miles to the gal. with no transmission slipping. feels great.
Ruck's if you PM me I have a 6 month old MP 8 box that I will sell that is being taken off my 08 cause I am tradeing up to a 2011 .
SMARTY... . My truck loves it...
MP8 graet little box for a bit of upgrade (and keep the emissions stuff on).
XRT - ate my engine ECM and left me stranded for over 1 month
Food for thought... .

Just an update. About 2 1/2 months after this I smoked the transmission. It was 100% my fault not the programmer. I have done alot more now and if I ever get any extra money(is there such a thang) will do more. :-laf
Best way to increase mileage? EGR/DPF delete and a programmer coupled with a light right foot. It'll make your engine/transmission last longer too.
Oh, and I too blew up my transmission, in part because I'm running a lot more power through it, but mostly because I was screwing around and did something I shouldn't have.
