Torco e85 tune

Hey guys,

Since e85 requires the injectors and fuel pumps to run 30-35% more fuel through the system many people have added some combination of a cam, low side, high side, injectors or even a full blown PI system to run full e85.

If you are tuned for e85 you'd have the AFR / timing / etc. used for the equivalent octane you're flowing through your system.

My question is: If you're tuned for e85 (and obviously have a flex fuel sensor) but run say 91 and then dump a bottle of Torco in there would the tune recognize the boost in octane and act accordingly? My gut says yes, but I'm not totally sure. Also, and this is the more important question, would the addition of Torco tax the stock fuel system as e85 does?

Lastly, in theory if you're built for it and you're running 100% e85 you'd be at ~110 octane + torco (128 oz. = 14 octane) = 124 octane. Is there diminishing return at this octane level or could you get some serious gains with this set-up.
