well today i was letting my car idle after i replaced the injector o-rings and realized my base fuel pressure was 44! I had it previously set to 29. I tried to adjust it but the screw on my AFPR was all the way out and it would not budge no matter where i adjusted it, unless i went all the way in it would go up past 60. Why can i not adjust my fuel pressure? I think this is why my car randomly stalls and runs like real crap on cold starts.

just a thought, but ... kink in the line? Some kinda obstruction...?

a kink in the FPR? its on the fuel rail and the fuel rail is stock. I have the stock return connecting to the FMU then out. Someone by chance told me if manifold pressure is high the fuel pressure goes up, don't know if there is any truth in that or not. someone let me know!!

If it is the begi/cartech fmu that will not allow your base pressure below a certain point. Use the big allen screw on top of the fmu and the afpr to adjust it down.
