All joking (From Me) aside, There are quite a few PROGRAMMERS/MODULES (learn those words) out there, Edge, Smarty, HTC(?) just to name a few, use the search bar, and do some reading on the subject to find out which one would be best for you. I have an Edge Juice W/ Attitude, It is all that I need for what I use my truck for, Do you have any Emissions/EGR Deletes? You might want to consider doing that before you put any sort of fuel mods on your truck...
