If you have 93 AKI (octane) street premium, run it and no magic sauce in a can.
We're stuck with 91 premium in Nor-Cal. But there are a few stations that sell 100 octane unleaded race fuel at the pump. It's pricey though. There's a 76 around the corner that has it, and the gas station on Andrade road in Livermore has a blending pump that you can pick 94, 98 or 101.
I can say, my 2011 911S really is happier on 94 than it is on 91. I get a little audible ping on 91. That goes away if I blend enough 100 in the tank of 91 to get to 93 octane, or just tank up on the 94 blend at the other gas station. Get more miles per tank as well.
I wish it wasn't so expensive. I wish 93 were more available. But our nanny state knows whats best for us.
Octane boost in a can is usually a waste of money.
Toluene is routinely added to aviation alkylate to bring 100LL up to 100/130 octane with reduced tetra-ethyl lead vs. the old green stuff. I know it boosts octane performance, but I think you need a good slug of it.

Just use top tier gas. I would not add anything. You don't know if the stuff you are putting in is compatible with the existing additives or your fuel system. With the finely tuned injectors in these cars, I would not start dumping stuff in the tank. With the .2s you could be adding to the already existing carbon problems of direct injection.
