Next step is adding a hood scoop to get cooler air into the engine, which hopefully will mean I can drop the octane booster and just run 93.

Don't let your guard down for a while if you put in the cool air. The AFR from the carb may change with a lot lower temp air..... it may get a bit richer or it may get a bit leaner....
