Can anyone point me in the right direction on my boost?

Right on. It is what its supposed to be if Im putting the info to my brain correctly. Now that I believe it is the issue this whole time. Because she spools blows of the steam. You know what I mean. My ? on the the vacuum now is the Turbo Pressure Assy. on the driver side inner fender the vacuum line runs from there to the cruise control acuator along the firewall T's into the intake nipple across the firewall to the heater vacuum somn or other I have looked and looked and asked trying to find where or what I'm missing because I believe my problem lies amongst that road. ????

Yeah read check that diagram posted above it's a good one and easy to understand. Make sure everything looks right. If your boost gauge is reading correctly then it's definitely a vacuum problem. Like I said you should have somewhere around 20 pounds of vacuum pressure at idle
