Spark plug recommendation
#2
I was running NGK Iridium IX Spark Plugs NGK-7164
My tuner said:
If your looking for max life span that is the best plug
If your looking for max power that is the worst plug
If your looking for normal plug life and max power use the NGK copper TR6 - 4177

What plug gaps do you use with E85 Ed?
Don't see too many guys running 6-series boxes (I'm assuming the OP is running an equivalent) on alcohol... Why not start small and increase the gap if there are gains? I forgot to mention in my prior post, I closed the gap from ~.030" to .024" when changing from -7 to -8 plugs and saw a consistent 1/4 to 1/2 mph gain, and zero change dropping to .022" or .018" gaps.
