    Those are a bit high, and you may require high octane gas to avoid "ping, or pre ignition, or detonation." Try some race gas just once to see if it smooths it out. I have a shaved head rebuild with 190 psi (doh!) that requires race gas mixed with premium (doh doh!) but runs like a raped ape with this fuel. Word.
