Why do you want to tune the car for higher octane than you can get?
Is this going to be a street tune or a track-only tune?
I can't really comment on the Torco stuff any more than "read the label" but it sounds like you might be creating a huge hassle for yourself by tuning the car for gas that you cannot buy. If this is a street tune I would stick with the 91 octane pump gas that you can buy, and tune it for that.
