I am also going to check out if I can find local 100 octane unleaded race gas. $$$ but might be fun. I’ve read that the DME can adjust timing to take advantage of up to around 98 octane (US), but I’m not 100% sure if that’s true or not. I miss MA where 93 was everywhere and 94 wasn’t too hard to find.

The royal purple stuff is low grade stuff in terms of the octane boost it provides, its worth about 2-3 octane numbers..so 91 to 93. Boostane and VP are the only ones that worth your while. Lucas is ok but not even close to being on the same level as a boostane.
you could get to 95 octane by just using 1/4 of a can of boostane...that works out to cheaper than the RP stuff too. Or a full can would get your 91 to 98.
I just picked up a 6 pack for $148 - I used promo code "newboost19" which saved me 10%
