Call a tuner and buy some tunes or ultimately build your own tunes. Every truck is different, hence efi-live is the best tuning software available. You'll likely not find the best fuel economy in your truck without extensive data logging and tuning. You will possibly change your driving style after you do some data logging, I have.
18-20 mpg is good, 20-22 is amazing, 22+ is not easily bought.

I am completely satisfied with the tune Les at silver bullet tuning did for me. EGT's are lower mileage is up and power is better than it has ever been. My lie o meter says 29.8 mpg. Haven't hand calculated it but I will and let you know.

With logs and tweaks, your truck can run very well.

I'm sorry, I couldn't resist. I had a 5.9 a few years ago that the lie-o-meter said about the same. It would hand calculate 18-20 depending on how I drove it
