Can you give some more specifics:

Is this a new issue?
Did it run recently?
Any work done to it lately?
Checked the obvious; plugs not foulded, wires all firmly attached, rotor and cap good, distrubutor not loose?
Timing checked?

Is this an Alpha or Bravo drive engine package? Gen two or three cool fuel system?

Actually anything over 43 PSI is considered to much fuel pressure and could be a sign of a problem, so an actual fuel pressure number at all RPM is important for diagnostic purposes.

If the fuel pressure is actually too high, and you have a Gen three/Bravo drive, Google Paint in the gen 3 cool fuel module. Eventually the paint gets to the injectors and having the fuel injectors professionally cleaned usually takes care of the problem along with removing the paint inside the module one way or another.
