SVO 30's at 90%+

Hi all, my SVO 30's are peaking over 90%. Does this seem correct for a heads and cam car at 13.0:1 AFR? I have the stock fuel system otherwise so im sure the rail pressure is a little low. does this mean its time for a new pump?

Honestly I'm not surprised. My stockers were at 100% with a smaller heads and cam, and after my 42s, they still go up to about 45-50% N/A.

Probably a pressure drop...that's what prompted me to go to 30-lb Bosch injectors on my bolt-ons only car. I'm gonna wait on the fuel pump until I have time - I get about 52 psi or so at WOT (down from 58).
