1st gen trd vacuum connections??

I purchased a 2002 Tacoma with a 1st gen supercharger. I am in the process of installing a boost gauge on it. I successfully hooked that up to boost port 1. It also worked on boost port 2. Both of my boost ports were capped off. That does not seem correct especially with the information I have found. Anyone got any input.

Also this has a little hesitation at wide open throttle.

 

The by pass valve should be connected to one and the fuel pressure regulator should be connected to the other with the boost gauge T'd in.

 

The boost port under the little 90 degree elbow thing is where the bypass valve should be connect. FPR and boost gauge to other.

 

Thank you. So now what goes to the port where I am disconnecting the fpr from?
