You should be able to do a little better than that. My 93 gets 15-16 on the road, 12-13 around town. That is with 285/75x16's and 3.73 gears. Engine is stock with a 3" cat back exhaust. My Dad was not much of an outdoorsman. Thought I was nuts for my lifestyle, when I was young. Wild land firefighter, 4 wheeling, rock climbing and camping.
We shared a lot of other interests, outdoorsmanship was not one of them.

I will be happy with whatever the mpg turns out to be...happy when I look at the rig and happy on the trail.
4.10 gears, big square body design, 6600lbs of steel, nothing to help me pass a pump :)

I know it has been a really long time since I updated this thread...just too much fun actually out using my Burb.
However I did start a new thread on my efforts to learn ECM tuning for my TBI setup.

Once it is worked out I will put an update into this thread :)
