Gauge Pressure vs Total Pressure

If I have an existing pipe flow with a real world pressure gauge (gage) reading of 56 psig and I want to convert it to an inlet Total Pressure boundary condition;  would it be correct to calculate as follows:

Total Pressure = Pstatic + dynamic pressure

--> Pstatic = Gage Press ( 56 psig) + 1 Atm (14.7 psi) 

--> lets state that dynamic pressure is basically negligible (.0002 psi)

then --> Total pressure = 71.700 psi ?

In addition, if I have "Pressure Potential" turned ON would that change "Total Pressure"  BC input
