Problem with pressure drop test...Need help!!!

I was trying to get the amount of pressure drop across the old intercooler before installing the abbott. So I t'd a vacuum gauge where the hose comes off of the turbo compressor into the solenoid valve.
The second gauge was connected to the intake manifold.
To my surprise the turbo pressure was reading about 4psi lower than the intake manifold.
At 5psi both gauges were the same. At 20 psi the turbo gauge said 16-17 psi and the intake gauge said 20-21 psi.
So how can I get the psi before the intercooler. I was hoping that this test would be easy.
Any thoughts?
