Stock wastegate boosting over 15psi??

I have a stage 1 in my car and my stock wastegate boosts to 16psi 2nd and 3rd, then boosts to 17psi in 5th and 4th. I use to have a complete stage 2 kit and boosted to 17.5psi with the stage 2 wastegte. Then i put the stock pcm back in and the stock wastegate only boosted to 13/14psi. Since ive put in the stage 1 its is 16psi-18psi. Does this sound normal for a stock wastegate?

The car runs great and im pretty sure im boost leak free.

You'll boost more in the hot humid weather, I get the same #s when its hot out.
