If I put 91 octane in can I run the 93 octane performance tune safely?

According to Bill, you can. I've never tried it. He says the tune is fine for either 91 or 93 octane gas. If it seems to lose power, it's probably pulling timing for the lower octane and if this is the case, I'd back the timing off in 0.25 degree stages (in the Custom Options Menu) until it "feels right".
