$10.00/gallon here for the Sunoco stuff.
Who says everything is more $$$ in Cali?!

How could you possibly know this???
Because bitog maniacal frugality/'pragmatism' 'trumps' the power train engineers' brilliance, EVERY TIME! /s

Possibly, but that does not imply, or preclude that the rest of their high powered/Hellcat level product does not have some sort of precise knock sensor feedback, spark timing advance, 'octane adjust ratio' Ford-like, program/algorithm written into their ECM's tuning.

I’m going to reiterate that CA 91 sucks.

No it isn't
It is operationally defined as resistance to detonation, as measured in a special test engine.
Of course it has other effects. Hardly anything is "purely" anything.
Old-stylee high octane fuel would tend to burn dirtier and fill up your piston crown dimple with deposits. Current stuff I dunno.

What does that do?
If the car is NA only thing I can think of is it advances the timing, (or, more likely, substitutes another timing map, because even my Lada had manual advance of static timing).
If its boosted I suppose it could fiddle with boost pressures.
Even then manual control seems a bit unnecessary and,..well, crude.
Don't get me wrong, I LIKE crude. Just seems out of place in a pricy modern car.
I suppose it does give the punter a button to press though.
I bet its RED, eh?
