Do I need an adjustable fuel pressure regulator? So I'm upgrading my fuel system, which includes new injectors and fuel rails. Well I got the Professional Products Complete Fuel Rail Kit. Will I need to get an adjustable fuel pressure regulator?

No not really.
You would only need an adjustable FPR if your injectors were so huge that you had to scale rail pressure down in order to control IFR at idle.
