It all depends on what mods you have (bigger tires, etc.) and your driving style. At that speed, the MPGs aren't too good.

You have a 07? I would think it would be a little higher.

A new exhaust will help, just in very small amounts. Did you go by the overhead console or did you calculate it by hand?

i know that thing lies, but i am afraid to know the real truth. I have heard that mpg increases as total miles increase on the hemi. any truth to that?

The overhead console is not always wrong, but it can be. It just requires you to reset it everytime you reach a certain speed.

and you do have to reset the computer.. if your rockin down the highway at 75 mph hit reset and it will calulate a more accurate mpg. but that does sound about right for that speed.
