My mistake, I used a BSFC of 0.55 and a PSI 36.
I'm going to install a TS SC, I'm assuming 0.55 BSFC.
If I recalc 500 hp. 0.55 BSFC and 55 PSI 80% duty cycle I get 38.21 PSI.
550 hp get 42.03 PSI. This is what Andrew saw.

11.4 afr at wot is damn near perfect and and has a good margin of safety on boosted 928 cars. 11.8's would be perfect IMO. I'm running 42lb inj. and that's where I need to be.

Sterling - stock LH2.3 = 3.8bar/55psi (LH2.2 = 2.5bar/36psi)
CHP = 725
#Inj = 8
BSFC = 0.45
Duty = 0.80
PSI = 55
45.34# @ rated
IIRC, injector flow rates are rated at 3bar/43.5psi, shorted open, but when controlled by an ECU, they never reach this rating.
