fuel economy ?

[bamboo]

so I have an OBS with AD codes, So figure I'd best post this here.. I pretty much got a newer SD under the hood, AD's, 17* hpop, SD turbo, and all that other good stuff
what kine of fuel economy you getting with bills tunes?
mostly you 6speed guys, But any one can chime in.

I Just got My 35" tires on and Now I have to be cautious to get 200 miles a tank, so thats roughly 12mpg
I can hardly afford to drive right now, partially cause alot of that money went to new wheels/tires
