Sorry if you posted it somewhere but when will VSRacing start selling these S480 clones? I'm thinking about using one on my LQ4 Fbody now after reading this.
Actually, I wonder if it'll even fit in an Fbody? Lol.

I would guess denmah just has the reference line removed. So no vacuum or boost applied means 58psi all the time as measured at the rail.
And roughly 41psi delta across the injector with 17psi boost in the manifold.

See the below screen shot of one of my logs. Fuel psi is roughly ~61psi at 2 psi boost. Then jumps up abruptly when my hobbs switch kicks the second fuel pump on but averages ~71.5psi at 10 psi boost(highlighted area). Same relationship has been recorded on 17psi logs.
