Hi Kellys, and WELCOME!! Far as exhaust I would recommend that you get it free flowing as you can (straight pipe, high flow muffler). You can't get air in if you can't get it out. For a programmer I have read that a lot of guys like either the Smarty or an Edge. You want to be able to add a little timing for better mileage, but the best controller for fuel mileage is just under your hat!! A light foot goes a long way, but it ain't as much fun....... I think you can go to a 315/65 tire without much of an issue. I am sure that others with more experience will chime in.

the size of tire depends on the size/offset of the wheel, you can easily clear 35''s on factory wheels without rubbing, granted every truck is different and depends on how you want to do things
