I get 11.5 mostly city driving. I have an XCal 2, magnaflow muffler and a tonneau cover. Nothing helps. It's been getting that mileage since it had 6 miles on it and no mods. Now it has 7500 miles. Hopefully this summer I'll make some road trips to see what I get on the freeway. It's pretty fun filling up my 36 gallon tank with premium. About $90 every 8 days or so.

You should be seeing 18+ mpg on the highway. Some folks have had their computer reflashed and noticed improved mpg's. A tonneau cover will also help increase fuel economy, especially on the highway. I noticed about 1 to 1.5 mpg increase when I put mine on. My best mileage was 21.6 driving at 60mph. I have the heaviest model too, an '05 Lariat Screw with 5.4, 4x4 and 3.73 gearing.
