What were you getting before all the banks? You should be getting around 17 highway unless you have duels and 4.30 gears.

Mine is in the 13-14 range with the big tires and completely stock. I used to get in the mid 17's with the tires, and stock. The dealer reflashed for the new FICM - now not so good.

Also - i would STRONGLY advise you on getting rid of the aftermarket intake unless you are out of warranty. The stock intake is good for 500+ HP, and it will void warranty due to "dusting" of the turbo. i'm sure there are posts about it - just an FYI

I get 12.5 to 14.0 - city or hwy - whatever I do with my truck.
