Question about raising base fuel pressure
My base fuel pressure (0psi) is currently 45psi. I'm running Denso NB-style injectors (DW 800cc) that love 60+ psi and a K-Tuned AFPR with gauge. When I went to raise the pressure to 60, the car leaned out from 13.5:1 AFR to 19:1+ and stalled as I approached 60 psi.
Why does it go lean at idle when I raise the fuel pressure?

Yeah, that.
The only time I saw that happen was with some crappy DSM injectors my buddy had that DID NOT want to run anything higher than 40psi pressure and became very unstable/leaned out as we raised pressure.
