e85 or 91 octane pump gas?

My local options for fuel have me questioning what to use. There are two gas stations close to the house that carry e85 and the car has to be tuned no matter what. All the local stations carry 91 octane premium at the pumps. I'm seriously considering having a tune for both. My only concern is that I will probably need more injector for e85. I'm being way indecisive or flexible depends how you look at it.:eek:

I don't know if I should build for 91 or e85 or go all out and set it up for both.

Just looking for thoughts and opinions.

Thanks,

Joel
