Does this sound right, I have a 2007 4door 4-1/4'' lift with 35'' mtz and it says I'm getting 12.4 mpg? What are all of you guys getting?

You're going to have to get a programmer to change the tire size in the ecu.
I'm assuming you're just reading your electronic display..? Try checking it the "old fashioned" way!

Did you try resetting the fuel economy guage by holding down the button. I thought I was only getting 16 and reset it and it went up to 18 or 19 mpg. It fluctuates between 16 and 19 now.

If you've reprogrammed your ECM, What tire pressure are you running? A recent survey indicated that many MT tire owners were running in the mid twenties psi which increases rolling resistance noticeably on tire 11-14 inches wide.
and mix netween freeway and sideroads,, not much city and I get 15.5 on average.
