I dont want to run e85 the whole time,just want to add a gallon or 2 to a full tank of 93oct just to help raise the octane a little when im running the car hard or on the dyno.
Probably get with HHP or Serious HP to discuss tuning, the stock hellcat fuel system capabilities.

We read about mixing fuels but I'd rather get some solid feedback from the tuners.

Could save you and your engine a lot of money.
