My guess would be, "Why does my gas mileage suck so much?", but I could be wrong.

A few questions from this end while we wait: What other mods do you have to the truck? Is this something that just happened all of a sudden, or was it a slow decrease? What size tires? Any lift? Have you tried different driving styles -- i.e.: light right foot on the loud pedal vs. smashing it at every light (as some on this board profess to do)? How are you calculating the mileage?

The 2500 is a heavier truck than a 1500, obviously. Are you a 2WD or 4WD? How long have you owned it?

Are you doing the math or going by the digital readout. If you let it run and warm up, it will kill the mpg as well as winter fuels get worse mileage.
