Here is an interesting idea:

Those who have a 2012 TI or I think virtually any 2013 that is designated as being able to use E85, I think they are tuned to scale better with higher octanes. E85 from my understanding has a much higher anti-knock rating, hence why people throw it in for race applications. The big requirement for engines to use E85 from what I remember is high pressure (Direct injection) and a tune that can scale the ignition timing higher to take advantage of the higher anti-knock properties, hence more power!
