Question To Much Fuel Pressure?

I just checked my fuel pressure, its set at 16psi. Is that to much for the list of mods I have? I know stock is 9psi. I don't want to over do it and I would check at the track but I don't go till Wen. Just thought I would get some professional opinions. Here is my list of mods.
