Message I have sport 550's, run race gas (100 octane) @ 20psi. I have a Knock Meter and as boost rises the bar graph just touches yellow, which I attribute to engine noise from the Ross racing pistons. I am just under 500whp and I am exhaust constrained, which means my boost does not build as fast as the pressure rises.
