boost gauge reading?

Finally my back ordered SPT boost gauge has arrived and its being installed today. Other than the SPT cat back that has been installed, I'm stock and on stock maps (for now). What should my gauge read as "normal". I've never had a boost gauge and never had experience with them before.

What shod it be at idle?

At WOT?

And during normal driving?

Thanks!

Good to hear you got it cleared up =)

That looks like it's tapped off the BPV control line, correct (judging from the master cylinder and booster in the background)? They didn't do a very neat job, that's for sure. I tapped mine directly off the intake manifold, but I have a bugeye, which is setup differently from yours, and none of my vacuum lines have loom on them.
