350 Stealthram Fuel Pressure for 24lb Inj??

I have finally finished getting my car running and I have been to the Race track two times now. The first time I went, I ran a 13.02@104. Yesterday, I ran 12.85@104. Since the first run, I haven't adjusted or messed with the fuel pressure. It is currently at 44PSI and I am running 24lb SVO injectors on my stealthram 350. The car seems to "fart" under part throttle but then runs better as the pedal gets closer to the firewall.

Anyways, here is my setup and I would like to see if anyone would have the best fuel pressure to set the car up to run a bit stronger.
-1990 350 Iroc-Z (Speed Density)
-Stock 350 block - only high volume oil pump and double roller timing chain.
-Factory Stock chip.
-ZZ4 CAM
-ZZ4 Heads, slightly ported and gasket matched.
-1.52 Comp Cams Roller-tip rocker arms
-Running ~12 Degrees advance
-44 PSI fuel pressure
-24lb SVO injectors
-Holley Stealthram Injection
-Stock 48MM Throttle body.

Sorry for the long info. Hope someone can help.

Thanks,
Pablo.

Those are awesome numbers for your setup!!! I would just tweak the FP up or down a little. I am running mine with the recommended psi from Holley (45). The AFPR that comes with their setup holds real well for me. Not one problem yet. Congrats!!!
