Pressure Fluctuations
I recently changed in-tank pumps due to my Aeromotive A1000 starving the pick-up at low volumes. Went with a Bosch 330 pump. I have 44.5# injectors and Fast rails and run 58psi.
Now on acceleration 3/4 throttle with full tank I get a brief pressure fluctuation from 58psi to 52 psi. The motor doesn't nose over, I can't tell any change in performance. It is a parallel set up with the regulator behind the injectors.
Should I be concerned with a 10 percent drop? Is this normal?
My Aeromotive stayed rock-solid 58 psi, but of course it moved alot of fuel.

What's your injector duty cycles when it drops to 52psi?
