Lyometer stuck on 12.8 MPGs

[02Oilburner]

Why does my trucks lyometer say 12.8 MPGs no matter how i drive. I get 16-20 MPGs hand calculating. Anyone else?

a) Its a lie-o-meter
b) You have to clear it at every fill up. Push and hold both buttons.

Yeah mine sits at 19.5 for the past 3 years It was 21.5 for a while and then dropped when I put the super chips in and beat the piss out of it every time I drive it. LOL What can I say? I have a heavy foot and I like to drive fast. Oh and I hear ya about the cloudy head stuff. I went to a local Hibachi Friday night, brought a six pack of bud and I am good friends with 2 of the chefs well One of them brought me a small bottle of sake and the other one was shooting sake in my mouth... I was trashed... It was a good time though!

Are you running stock size tires? If not, has the computer been updated?
The MPG computer seems to lose its mind once a chip/program has been put on the truck.

hey fgtex, did yours lose its mind with the dp tuner as well? Both my superchip and diablo did it, but i have been curious as to what it does with the dp tuner.

I do not have the overhead computer on my truck. I have read many times on these boards that the MPG readings tend to be way off after a chip has been put on.

Mine was stuck at 12.8MPGs I reset as instructed and on hwy it says 21MPGs.
Im running 285/75/r16 but Jody adjusted my DP-Tuner for that size tire when I ordered it.

have you noticed any difference in how many miles you get to the tank when he recal'ed your speedo?
