Wondering if there are any places around Tacoma area that got higher than 92 gas..? Not looking for race fuel or anything
High Octane gas?

There's a Cenex station just off of Auburn Way S., that has 94oct, and a Small& Sons 76 station further north, that has 101 unleaded Trick at the pump, but that shit will hurt your wallet bad! ($8.25 per gal.!!!) The 94 at Cenex is just the normal 92, with about 10% more ethanol (which raises oct).
Am I gonna be able to run E85 with a walbro, 440, AFPR? or should I just mix lets say 5Gal with 10 gal of 92 Octane?
Just some basic bolt ons and a bit over 1 Bar of boost, figured it'll be safer than running just 92 Octane. Plus I'm running lean right now for no reason, which doesn't seem safe to me even when I'm not boosting. Got a bunch of other internal parts do go inside the engine whenever I have time for it, if that means anything.
If you don't need it due to either boost or timing high octane is going to make less power and cost more so doesn't make sense.
I see. Wouldn't you agree that running 20 PSI + will most likely cause Det on 91/92 Octane than?
Btw, thanks for a straight answer, grumpy old guy ...

Too many variables to say for sure, I run my motors up on the dyno adding more boost and timing and listen with a set of electric ears then base the final settings on this.

when Im not making boost I usually run anywhere from 14.00 - 17.00 A/F and I havent run into any related issues. When I start to make boost it drop way down 10.10 - 11.50. As long as your not running super lean under boost I wouldnt loose any sleep over it. Unless your running way lean like 20:1 while not boosting, then I think youve got a little more than not enough octane in your fuel tank
Well, I'm not running that lean 
Doesn't matter thu, I'm down in Georgia now, they got 93 Octane :
tell you what thu, that drive up in the mountains with temps around -15, -20 was awesome, think I picked up like an extra 50 to the wheels, lol.

Yes, I did lost power, and started to choke in boost (was pretty bad at 6k feet), but when I went down and temps were still cold as s**t, I gained a bit

To OP: You should check the duty cycle of your 440's at that boost level.
Double check your fp also. You'll want that set to the TSRM spec.
