You say 35 psi, then drops to 7 - pretty sure that's low in |

both cases. I'm used to seeing a diff fuel pressure of 45-50psi, but even so, the fact that it's dropping off like that is kinda wild. You have the FPCU bypassed? Given the size of your injectors and the power you're putting down, I expect you've got a beefier pump that won't play nice with the FPCU.. That said, I also know Scott is known to make some substnatial numbers with lower-flow pumps (recommended a Walbro 255 for me, which I have), so mayyyybe you still have the FPCU in and it's having fits?? Worth the ask. I left my FPCU alone with the 255 until just recently when I decided to eliminate that as a potential contributor to my minor idle bounce issue and for future work, too... especially considering it's one of the easiest things to do on the car. Would be interesting to hear what Scott has to say. When it comes to fueling, he knows his stuff.
