Wow Guys, I feel so much more smarterer.

What a read.
Way too much for me to absorb it all.
But my general gist of it all is:

50/50 water methanol mix is best "all round" ratio.

Tune car for max power at best air/fuel ratio without knock with no injection (12.5/1)

Add injection and then reduce fuel to bring air/fuel ratio back to optimum

Advance timing to gain more power to just before knock

For more power after that either add more fuel or injectant

Have I got that right?

I am off now to soak my head in a bucket of ice water for an hour or so. LOL
