Torco Mach 112 Octane Stoich point?
Who cares? Normal pump gasoline probably changes throughout the yearly summer/winter blends more than the difference you are looking at. Besides, no one runs race fuel at stochiometric anyway. Just tune for what your motor likes. If this was a purely academic question rather than a real tuning question, I apologize for the non-answer. If this question WAS related to real tuning, you need to do a lot more research.

You do realize stoich point of say, VP 109UL is 13.6:1....which is clearly outside any blend of gas that has been certified before shipment.
This question is the difference between life and death of this motor, why you ask? It's being blended with an alcohol based fuel. Knowing the stoich points of the two mediums is a must, regardless of what, "everyone else," does.
Please refrain from attacking people who clearly know what the hell their talking about.
