Hi Bill,

     Yes, my pressure is a bit higher than stock at 43 psi.  As a matter of history, when I first flew I was using MSD 34 lb/hour injectors and they were flow rated at 43 psi fuel pressure, so that is what my fuel pressure gage is marked for, and my pressure regulator adjusted for..  A little bit more work for the pumps, supposedly a little bit better atomizing of the spray, but I don't think my higher pressure is really significant.  If it were 50 psi or higher then it might be a different matter.  Just my opinion of course.
