I have a 4.7 CA smogger, running 55 psi on the fuel rail, with 30 lb injectors, 2001 intake, 2.5" exaust, header, comp cams cam, 4.2 crank with 4.0 rods setup.
Any info would be appreciated.

That gauge is showing rich. Why are you running 30 lb injectors? Those are way too big.
Also, more details needed.
