2004 MPG w/mods NOT GOOD

Whats the deal with my truck? I see all these stories of guys getting 20+ MPG. The best I have gotten on one tank is 365 miles, coming out to 14 MPG (hand calculated). Now thats a mixture of town and highway (plus putting my foot in it every now and then). You can see my mods in my signature. Also when I fill up, after my dash light comes on, it usally holds about 25 to 26 gallons. Is this normal or is there something else going on?

Forgot to add that I'm running Eric's Extreme Street everyday.

I run 38" tires with 4.56 gears, 8" pro comp lift and on the freeway I can manage about 14.5-15mpg at best running RPMs at 2k or less. Roughly 65mph. Around town I get about 11-12 mpg if i keep my foot out of it. I have erics extreme tunes too.

I guess I'm not to far from you all on MPG. I was starting to think I had a bad injector or the fuel pump was going. Thanks for the replys and keep em coming.

I am usually 14-16MPG. Craziest I've seen was 21 MPG, going 50 MPH for a 1.5 hr trip

I would say I'm 50/50 city/hwy driving. If I pull a trailer, its less.
