Boost Gauge coming up short...

So i installed a boost gauge a few days ago and its not coming up with accurate numbers. I have the FS/VF supercharger kit, so first i put the vacuum line from the gauge in the line that runs from the bypass valve to the vacuum line that runs into the intake manifold. Then after the gauge showed no more that about 2psi of boost i figured that i had it in the wrong spot. SO i moved the line to the actual IM line, with the same result. My blower is putting out over 9psi but the gauge wont show more than 4psi. To test if it was my gauge i hooked up my buddy's boost gauge and it showed exactly the same thing. Any ideas? Im assuming that i just have it hooked into the wrong spot.
Thanks guys

How do you know for sure your blower is putting out over 9psi?

I always tapped in directly to my IM, or added a bung to an existing connector to get my boost readings.

2 gauges and showing the same more then likely thats what the boost is

There is a Vac line running to the pass side going to a round black unit (EVAP) take this off the EVAP and use this as a dedicated boost line

I know that my blower is putting out over 9psi because when i took it to randy at FS to have it dyno tuned vic hooked up a boost gauge and i saw it read almost 10psi when on the dyno.

and the evap... i like this idea... is there anyway i could get a picture? Thanks!

Is your idle vacuum reading fine? I had the same problem after I re-routed some wires/vacuum lines and the cause ended up being a kink in the vacuum line going to the gauge right where it enters the back to the gauge.

18-20 inches of mercury is normal.

Hmm...I wonder if you have a kink in the line going to the gauge or something. That much doesn't really make sense to me, although it is possible. Does the gauge zero out when it's off or does it stay at 4 or 5 inches of mercury?

The line is straight all the way through, and it Does zero out when off. I know its very strange. And today when i was driving home, i punched it, and made sure the bypass valve was totally closed so that all the boost was going in, and nada. Didn't even show any on the gauge at all. And the line is tapped into one of the lines going straight into the IM. It just doesn't make sense.
