Do you have any codes present? How is your power and economy? Having run such consistently low fuel pressure (7psi idle, 5 psi cruise, 0-3 psi WOT :shock
, I would be very concerned about damage to the the VP44...
Over time, low fuel pressure to the VP44 can damage the diaphragm in the front of the pump, causing the timing piston to vibrate. The rotor may also have issues, causing cavitation. The increased fuel pressure from the Raptor pump may simply be bringing existing problems to light.
