VAFPR Question in concern to the EBL, Calling RBob...

Hey guys I have a question. When setting my VAFPR am I supposed to set the fuel pressure with the hose connected to the vacuum line or disconnected?

I'm guessing connected right? As vacuum decreases the FP should increase correct?

So I'm going to guess that all of my popping out the exhaust from a rich mixture is going to magically go away once I do this...

Possibly. If you ran VE Learns that should have dropped the VE table to make up for the excess fuel pressure.
