Optical would be whatever octane you tune it for before it starts knocking and pinging ... its hard to say what its tuned for stock because the ECU is the learning type so it can adjust itself to whatever premium gas is avaliable to it. You could say that its tuned to 91 and will increase performance with 93 as it "learns" it or that its tuned to 93 and decreases performance with 91. Whatever works best for you I assume.
