Just Bought a 2007 Cobalt Ss/sc

Hey everyone. I'm back but this time I've got an ss! Anyways just bought it. I thought stock boost was 18psi at wide open throttle it's hitting 18psi. It also seems a little rich.

I had a HP tune, intake, header and exhaust along with stage II. I peaked at 12psi and fell back to the 11's. Definitely not stock you are

How can I tell what's on it? The pulley bolts are light blue if that means anything.
