Is 14mpg bad?
I have been getting 14.0 - 14.5mpg ever since I bought my 93 pickup w/22re a couple years ago. Since then I have fixed/installed a few things like new headgasket, lce header + midpipe.. but mileage stays the same and occasionally dips in the 13's if I forget to unlock the hubs when I'm back on the street.. granted I do rev the piss out of her and like to stay in good rpm range, I just feel like there's something I'm missing that is robbing me of a good 4-5mpg at least...?

My '87 with 4.10's and 10.50-31's gets about 21-22mpg in mixed driving.
The '88 'Bluerunner' I rebuilt and sold got closer to 24mpg.
Maybe O2 sensor, or not going into closed loop?? Any codes set??

Sorry forgot to mention I have 32's with stock gears and no codes, also replaced the o2 sensor with the best suggested brand/type (don't remember brand).

32's shouldn't drop it that bad, if you were getting 18mpg I would blame the tires, but I would say something is not right to get that poor with a 22re to only be getting 14. I get better than that pulling a trailer with mine with metric tires that are as big as most 33s (albeit narrower) and 4.88s. Without a trailer I will get around 20, with one I usually get close to 17 (obviously depends on the trailer). If the sensor to the airbox (don't know what it is called) isn't working right it will cause them to suck the gas, but I've never seen that not throw the check engine light. I ran a previous 89 for years with the wires disconnected from the O2 sensor and it never affected the gas mileage (did have a check engine light) but I know it made a very noticeable difference in my Tacoma when the O2 sensor went.
I will say I have owned five trucks with 22re motors, three extended cabs and two regular cabs, all five speeds (automatics usually get noticeably worse mileage) have ran anything from small 30-9.5s to some 34 inch super swampers and while every one seemed to vary a bit from the others none of them approached the mpg you're getting unless I was bucking deep snow.

I think I have a 190 degree thermostat, but not 100% positive. I'm about to drill a small hole or two in mine anyhow because it likes to act like it's going to overheat when I'm first driving down the road on a cold startup.
How would the thermostat effect mpg?

The four biggest factors for mpg that I can think of are engine health, gearing / tire combination, excess weight being carried around, and driving style.
You mention that you continuously rev the engine.
Maybe change your driving style a little closer to "elderly man driving a Buick" and check your fuel economy again.
Just something else to consider.

This tank I'm on a roll. 206 miles and I still have that "1/4" left.
Used to have 16.

18 to 21 MPG, with 31-inch tires, mix city & highway with a little dirt roads. Checked against Speedometer GPS phone app.
Next time I drive mostly highway, I'll monitor again.
