NOOB Boost Gauge Question

NOOB Boost Gauge Question
Ok so I finally got my boost gauge in for my S/C. I have it wired in to a 12v source running to the stereo that only powers on when the ignition is engaged. Now there are 3 wires; 1 for 12v lighting, 1 for ground, and 1 for 12v ignition switch. I have both 12v wires plugged into the same source. The boost tube is a 1/8" clear PVC tube running from the gauge to the vacuum line running from the throttle body, I have it connected via a T fitting. I checked for kinks and any pressure points on the tube and it's clear. I checked my power and it's clean, both 12v and ground.
My problem is that unless I am pushing more then half way down on the throttle when accelerating it doesn't register boost, just idles at 0. Under cruise control at say 65mph i have 15vac. I thought that throughout the RPM range on the supercharger that even if you aren't under acceleration you are still making boost? I know it's working ok when reading max boost because it peaks at about 6psi under hard/max acceleration; i'm on the stock pulley. Also when I am sitting still and waiting for the car to cool down the needle jumps between 0vac and 20vac pretty fast and makes a nice clicking noise.
Is this normal? Where have I gone wrong? Different gauge?
I have this gauge:
Should I just get this gauge so I have a # readout instead of a needle?
