Any insight for as Cali guys that are forced to run 91... I feel like on track days the 100 properly mixed with the 91 would give us better results..
Approx goal would be to reach 93-94 octane.

The car, as far as I know, is programmed for 91. Pretty sure that's the octane listed in the manual too.
Anything higher would be a complete waste of money.
In general if a vehicle doesn't knock/ping on octane X and you change nothing about the car then anything higher than octane X is 100% useless.
