Sorry to hi jack this thread ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Currently I'm running a P1SC-1 with 42s, one 255 in tank, and KB BAP. I'm running out of fuel (starts to lean out) on the top end at around 5000 rpm making 8psi, and the fuel pressure drops from approx. 60 psi to 45psi (this is unacceptable). The injector duty cycles are over 120, I think Im running out of pump, I cannot see going to 60# injectors as I have stock heads and cam.
I have seen others run around 5 or 6 psi with a racetronix and BAP with no problem, but they are staying in the 470 to 500 rwhp range, I think I'm going to be over that.
Let me know what you think.
Later,
Max
