E85 with JB4?

Newbie question here, trying to see if i can squeeze any worthy power gains from my (already maxed out?) set up. I am currently running JB4, intake, catless downpipe. I usually run map 2, 3 or 5 but noticed map 2 is probably the smoothest and most linear. Is there a map which supports partial E85 (say if I want to throw in 2-3 gallons)? And if so, is this reccommended/worth it? I have not heard of anyone doing this when I searched.
