FSM Click me for 4g15 1.5L and 4g61 1.6L fuel pressure specifications

This is the tool in question with a gauge threaded onto the top via an adapter sleeve:

Being as I have never adjusted an aftermarket fuel pressure regulator as of yet (still have one on the shelf), just want to confirm adjusting fuel pressure per the manual here:

Going here to confirm pressures Click me using 6th gen GVR4 specs (2.0L but turbo), you get 27 psi vacuum hose connected, 36-38psi with it disconnected. Other turbo DSM's from this era specifically seem to use the same (27 disconnected/36-38psi connected) spec.

So, for a 4g61t stock fuel system, 36-38 psi should be good (vacuum line disconnected), yes?
