boost gauge reading, curious

[speedtrapped]

well since some have seen my recent thread on my boost gauge install, i have been watching the gauge at diff levels of driving, I have not ripped engine real hard, really just touring, but max boost i have seen so far is 5 psi-7psi.....so what is "normal boost pressure and max" for our cars?
TIA

You should see somewhere between 15 and 17.5psi at full boost.
