I hear your the best e85 guy

I was wondering how much I could gain changing to e85?
Can you pump timing up on e85 like you can on 104 race gas?

I have
C&L street cai
ud pulleys
delete plates
mac long tubes-no cats-stock h pipe-ford racing stingers

made 306 hp and 322 tq on 93 octane dyno jet dyno

I think I will need bigger injectors(39's?) and a boost a pump?
