well the lift and tires is def not helping.. in order to get better MPG your going to have to start deleting some of the restrictive smog crap...

so my suggestions are:
Intake
DPF delete exhaust
and a tuner (H&S, SCT or Spartan)

Better then what you are getting now lol. It depends on your driving really. Some guys are seeing close to the 20's but you do have bigger tires so ya.

My 2 cents, if your looking for mileage get a Ford Ranger, if your looking for power stay with the 6.4

You should consider yourself lucky if you get 12.5 mpg with that size of lift & tires. I only got 12 mpg hwy with my truck stock height and tires. S&B, dpf delete, and Spartan 250 got me up around 18 mpg hwy stock height and tires. 4" lift with 35" tires brought me back down around 15-16 mpg hwy. Only way to improve mileage is to get rid of dpf. To do that you will need a programmer.

Like a few stated above, deleting the DPF/DOC and adding a tuner is the best route to take. I recommend:

1. AFE or S&B cold air intake
2. 4" or 5" downpipe back exhaust
3. Spartan Phalanx/DashDAQ tuner

We are running a few Memorial Day specials through the end of this week that you might want to check out. Let me know if I can help or answer any questions!
