Reviewing posts am I understanding correctly you can run up to 4 gallons of E85 in a full tank with the rest 93 octane for more power? Just installed JB4 and was thinking of trying. Do you need to adjust any specific JB4 settings if using E85?

Also one more question; sheetz right by me the flex fuel says 51%-83% ethanol. Is this the same as E85? Do you have to change the mixture depending if it's 51 or 83%?
