Returnless fuel system ?
Since the returnless system has the regulator mounted directly to the pump module, how does it get it's signal ? I know it's electrical, but is it something in the PCM, or what. I have searched the FSM, and there's not much mention of how it works, or how can you change the pressure. If you were to install a system like the APS Twin Pump system for the GTO's, woud it set some kind of code?

You will be adding a return line and external boost/vac referenced FPR with the type of setup you are talking about. So you will need to change the IFR table in your tune.
Looked at their install guide and I'm not sure how they keep their "surge tank" filled.
