Still if you add some 100 or better to a 93 tank and you are tuned on 93, you are going to get some level of knock protection over just your standard 93. And you would keep the timing you have rather than losing it from a bit of knock. If I were 93 tuned and heading to the track, I'd always want a splash of 100+ or octane booster to help keep the car consistent.
