Not everybody can get away with 23psi on 93 octane, as that would require an excellent tune, and J&S safeguard. I would recommend 10-12 psi to be safe on 93 octane.

I've been running 13psi on my stock ZETEC block with SVT internals dropped in. But my CR is different i have around 8.9:1 CR, so that changes the ball game
