Tuning for high octane "730" ecm

So how much power could be had with tuning with race gas vs say 91-93 octane. I'm building a 355 195afr comp ported, 10.5ish/1 compression xfi cam 224-230 112 cam, HSR with full bolt ons and will need lots of tuning vs the tune I'm running on my setup now. Been thinking is it worth mixing rave gas and tuning for it vs premium pump gas? The truck is going to be a weekend toy.

You wont see anything. Chance of a few more hp if using an oxygenated fuel or maybe e85 as it cools intake air slightly. But not worth it

Take the cup out and gut the internals and replace with small washers or nuts
