From an update on this thread:
Murf's Methanol injection install
JM, a Toyota master tech and part time mad scientist has added several upgrades.
1) Added the ability to independently switch off boost from the S/C and also the Methanol injection. This has really allowed to use the boost yet save burning through the method fluid as I would previously. Had to creatively move the green activation indicator light and the red low fluid light to keep it all together.
2) Modified the windshield washer . I had the 80's much larger w/w bottle directly feeding the smaller 1 gallon Snow provided method fluid bottle. As anyone running meth knows, it gets used quickly if not careful. Pushing the front washer spray button would refill the snow bottle but I lost the ability to spray the windshield which wasnt needed frequently but a PITA when it was.

Now that function has been restored and the rear glass spray function on the stalk is what fills the bottle. I use that about once a year, so no big deal for me. Amazing how the little things are appreciated!
3) long story but JM found out that the 80 has a two speed fuel pump. After the computer sees 3-4 seconds of hard acceleration it increases fuel pressure to the engine. I'm guessing the engineers didn't want it to kick in unless really needing it for more prolonged needs like towing or accel up an incline. No reason to switch it to full pressure all the time, you can see on the scantool that the ecm will slowly compensate and the advantage is lost.
So...some manipulation of the resistor and you can make it activate the 2nd speed almost instantly and drop back down as soon as I decelerate. Not long or consistent enough to give the ecm enough time to remap and compensate. Seems to give a little more kick off the line when getting on it.
Its the details that make the difference for even more driving enjoyment in my 80
