Change the piston! But running race gas only does 1 thing- cost you money! Better to just run 93 or 94 and leave it alone! Race gas doesn't help HP unless you run oxygenated fuel.

Exactly. High octane doesn't equal high horse power. The compression is where the horsepower is at, you just need race gas to have high compression.
