Congrats bud. Very nice truck. All I have on my 2013 fx4 with the 3.55 rear end is an sct tuner. I have it set on the 93 tune and it improved my mileage some, especially on the highway. I do a lot of highway driving. I'm getting 19.2 mpg when running 75 on the interstate. It did wake it up some too. I was getting 17.8-18 stock on the highway.

Nice looking truck. Gotta love Ruby Red. I would start off with tinting the front windows and adding a tonneau cover and bedliner. If you are into performance, the natural progression starts with CAI/exhaust/tune.
