With the 928 impeller and the 9lb pulley I bet you see closer to 11 psi. Also, if I remember correctly, the 9lb pulley is a 2.87. You can measure your's to verify what you have.

Maybe should mention what else you modded to fit the 3.47" and 3.0" pulley on the SC belt side. IIRC you needed pulley spacers of a certain size and needed to change the idler pulley on the SC side as well? To make this combination work or no?
And that you have a turbo guard instead of the K&N air filter to be able to make the 16.4 psi, since I'm not sure if everyone is running with a turbo guard or not.
