What weight oil are you using? Speed Inc. just built me a boost 347 and told me to run 20W-50 Valvoline VR1 oil. I imagine if they recommend running 20W-50, they have them set up with quite a bit of clearance, so running a lighter weight oil would hurt drop your oil pressure considerably.

The factory "gauge" is not very accurate. Modifying the factory pcv system with open breathers and such could also impact windage and crankcase pressure, changing things. As far as actual oil pressure being affected by a turbo install is unlikely. Except for a mechecnical problem such as excessive bearing clearances or something.
Also there was a bulletin issued by GM in regards to Mobil 1 oil and oils that have the "energy conserving" label on the bottle. Do not use such oils in lifter and pushrod engines. Including late style roller lifters. Royal Purple served me well in the past.
