2017 AWD Dodge Challenger GT - can it be modded?

[MPGomatic]

I lucked into driving the new AWD Dodge Challenger GT this week. It has the 3.6-liter Pentastar V6 and eight-speed ZF automatic. AFAIK, the engine is not FlexFuel-certified. I'm wondering what needs to be swapped in to make it FF-capable and what can be done to improve performance and efficiency on high-octane fuel.

This was a crazy drive …

For some reason this 2nd generation of the 3.6 that first showed up in the 2016 Pacifica is not E85 but the previous 3.6 that came in 2011 is.
