iss-4 fuel pressure

Ok just installed an iss-4 and its reading my fuel pressure about 20psi lower then my gauge is this a setting i need to adjust?
Its a new haltech sender.

P.s I changed the gauge out with a new turbo smart one and it reads the same

From the fuel lab gauge...

It could be your haltech sender...

Highly unlikely. They're high quality TI sensors.
