Got in the garage this morning and this is where I'm at.

Fuel pressure, cold, key on engine off 48 psi.
Idle 44 psi, stayed there as it warmed up.
Remove regulator vacuum line 53 psi.
2000 RPM 43 psi.

After shut down stayed at 48 for 10 minutes, disconnected pressure gage after that.

Took some catalytic temp readings

Driver's side
Front of cat 380F
Rear of cat 650F

Passenger side
Front 350F
Rear 460

Still making me think a problem with the cats. OR is it running way too rich on the driver's side and causing the cat to work harder and causing the higher temps?
