So E50-E60 in a proper spray window vs trying to stretch the fuel system to E80 and spraying past the spray window will equal no gain or actually a loss of power up top.
Just a word of advice. 6.5ms at redline is the beginning of the area where you start to lose power up top from improper mixture and burn. When it gets cold out, you will be in the danger zone and the engine will start to detonate and/or misfire due to spraying too far into the compression stroke. This is when you start breaking piston rings.
I'm not here to tell you what to do. I'm only trying to provide some information for you to consider when you make your choices.

I appreciate the info man!  I'll keep on tuning and see if I can step it down on the fuel side.
