I did check out Holley, beyond the $500 price, the "low" pressure still seems too high.
From what what I can find:
New Gen3 pumps ~1600psi
Holley "low" pressure ~ 1200psi
Old Mopar range ~700-1200psi
Toyota pressure valve ~750psi

I did the Mopar Action trick and added a couple of shims to my Saginaw pump valve and it definitely helped.
So I'm thinking I want to keep it in the ~800psi or lower range.
