How it?s going, I have a 2018 Camaro ss 1le with an lt4 blower, the other day I noticed my car sputtering at WOT I data logged it and found out my hffp is not matching the desired pressue. It was going from 2800 psi to 1300 psi and fluctuated which caused it to sputter above 5k rpm. My question is I just changed my hffp and at WOT, it?s not sputtering anymore however I?m getting a steady 1800 psi and not the desired 2900. If I do the same pull with %50-%60 I get my desired fuel pressure of 2900 psi? What could this be? I would greatly appreciate any advice here.
