Mercury 4,6L Flexifuel

Hi!
I use to use 91 octane tune in my Mercury when i fill it upp with 95 octane here in Sweden, but now i changed it and start to use E85 Ethanol (105 octane). Do you think i should change the tune to 93 octane or higher?

Yes, you can use the 93 tune with the E85 in the tank.
