boost gauge hook up

[9350coupe]

where do most of you guys hook up air line for boost gauge? How much vac should gauge be reading on average?

There is a spot on the vaccum tree (on the firewall) just remove the plug and connect it there.

I see 13 vaccum at idle, my cam sucks (custom is on the way)
