MPG's suck!! Need suggestions please!

Ok guys, I have everything in my sig done to my truck. I still have yet to see 400 miles out of a tank! What's the deal with this? I figured with what I have, I would see somewhere around 15-17mpg's at least. Any suggestions on what to do to get my numbers up a little bit?

Thanks for the help guys

Hmm.. Keeping your foot out of it?
And if it's in-town driving then it's going to kill you. It's pretty hard getting a 9,000+lb truck rolling. lol.

Only thing I really could recommend besides what you have is getting your FICM tuned.
I've heard it helps 1-2 in pretty much all cases.

Dude, I dunno.. Somethings wrong there then..
LOL.. I get 22 on the highway and about 13 in-town.
Maybe you're not calculating it right?? (I am in no way insulting your intelligence. lol)
You may have some stiction built up in the injectors but that wouldn't cause THAT bad of MPGs

Maybe I should try some Rev-X just to see if it helps? I am willing to do anything to get the numbers up.

i used revx in my last oil change. i was thinking to myself "did I really just drop $80 on a beer can worth of oil?"
and now I'm really glad I used it. Truck starts like a champ and runs like a beast.. No matter how cold it is.
