Wow you have a 2wd and that low of mileage. Hmmmm.
No ideas here unless all your tires are really low and soft.
I replaced my injectors several months ago and the mileage didn't go up but maybe .5mpg.

Does the hypertech scan for codes? Pretty sure you have a problem with something. I have never seen under 14mpg averaging out a tank even pulling and hotrodding around. I'm sure somebody with similar experience will chime in soon.

I have an 03 f250 4x4, and pulling the horse trailer I have gotten between 10.5-11 mpg. stock or with the hypertech. I don't have oversized tires or a lift kit.

The lift and tires will kill some milage - but on a 2wd that still sounds a little low... I'd agree with the other guys - something is a little off...
Also - I'd scrap that "drop in K&N" filter in your sig REAL fast!!

How long of trips are you going on? That will affect your mileage as well. It seems that going empty for only 15 miles back and forth to work I get about 13 but if I drive further distances (less stops ect.) I get better gas mileage.

Whats your boost #'s? I don't have a lift but when I took off the 33's that came on the truck and went back to stock it brought it from 13 to 15 then I went hunting for a boost leak and now am at 18. Hopefully when I get some mods done this winter I can get it over 20. The warden is finally letting me feed my PMS
