So very soon here I'll be doing my plenum and replacing a bad pre-cat o2 sensor. I'm currently getting 8-9mpg. Hoping to get at least up to 12mpg area once it's finished.
Sound plausible? Might just do a whole tune-up while I'm at it.
The only way I can get my (5.9l 4WD, sporting 265/75 all-terrain tires) truck down to 9MPG is to get all kinds of stupid in city driving. My usual level of stupid, when I go there, will get me down into the mid-10's. Without going stupid, I get 12-13 city. I could probably gain 1MPG just by emptying my toolbox but that's something I'll never do. On the highway running 75MPH or better I get 15+ depending upon how much headwind I encounter.
So, yeah, it's realistic with a good tune-up but those taller tires of yours might get in the way if you're spinning 3.55:1 gears.
