Welcome to DF.

8.8 huh? That's odd. I get around 13mpg with me hammering the throttle A LOT. What all do you have done to your truck? What size tires are you running?

I would suggest to get some gauges first, 4" down pipe and exhaust, and then a tuner. I would go witht an SCT with custom tunes.

an 05 getting crapy fuel economy? Is your truck all wheel drive? M/Transmission or automatic? Gearing? Whens the last time you did your Preventive maintenance checks and services. Fuel and air filters fine? Like 97 asked what are your tire sizes. and finaly is throwing any codes?
