Questions for those with a 93 octane tune

Agreed. Once you run e85, switching back to 93 make the mustang feel very underwhelming.

Back when I would switch back to pump for maintenance or out of necessity for whatever reason I literally couldn't get through the tank fast enough to get back on e. Night and day difference in power. The one thing I will say is those pump tanks last forever, higher mpgs yes but also just needing that extra power / response back made it seem even longer.

300+ miles of boredom!
