560 on 93 to 714 on E85. Stock '04 motor
150 gain on same boost level is pretty crazy. My gain is 154 wheel.....but that's going 18psi to 22psi and a ton more timing across the entire rev band
Some people will want ULTRA safe pump gas tunes, so you could see huge swings to the ethanol tune. Others will run much riskier pump gas tunes....so those swaps might not net as impressive of a change.
That's what I'll be doing, Robert at Vendetta is getting me the e85 startup tune tomorrow and when I go back for final tuning I will be getting a 93 and corn tune on a Moates chip. I imagine the swing will be huge haha.
