is this as good as it gets? please advise!

That sounds about right.

Sounds a little low to me. I am running the 1.22 R&D tune with a S&B CAI and just the delete pipe and I am getting about 20-21 mpg's on the highway running 70 mph. I have a job 3 F450 also with 4.30 gears. I found that the R&D tune gave me about 4-5 more MPG over the standard 1.22 tune.

my lio-o-meter reads 16-17 mpg, but when hand calculated i get 12, going about 70-75 mph. i'll give it a shot though, did you have any issues with CEL?

I get the "P2263" sometimes once a week and sometimes everytime I drive it . My lie-o-meter is not that bad, it reads about 1.5 mpg more than I am getting hand calculated.

doc311 - I don't have the SCT, but with Spartan 210 the best I can get out of my truck with 4.10 is 15.7 at about 67 mph. Before the tune around 12. Is your truck a 4x4? Welcome to the poor mileage truck club.....
