I have almost your same truck with those mods, and get the programmer first! it will show the biggest difference in performance. and I agree with the Gotts mod for your truck, its simple, easy, and really cheap compared to a commercial CAI. I got the Gibson exhaust, just a cat back, and it works fine, noticed a little difference in performance, and a good difference in sound

. I am running canned tunes for hopefully not too long, but they are working fine if you decide to do the other mods before you get the gryphon. hope I helped
