Boost drop with headers

I installed headers last fall, and today I was going over the one scan that I did afterwards. It seems that boost dropped from 11-12 psi to 7psi.
Doesn't that seem excessive?

Yes. I dropped ~1lb, maybe a little more. You must have had a major restiction in the exhaust setup that you no longer have.
