Sorry to resurrect the thread again, but I've been having some LPFP issues after installing the PR Stage 3 kit. I have the blue lpfp top, so I figured fitment issues wouldn't be a problem, but it was. I'm in the middle of getting tuned by EQT and they kept telling me to check the O-ring or venturi installation. See an example of a bad log below:

I really don't know what to look for on the log to verify fuel pressure drops, so I've just been looking at my LTFT and STFT% and if my STFT% sky rockets, then I figure I have a problem. Is this correct or is there another way to check it??? After removing, running logs and installing the lpfp about 5 times, I finally zip-tied the lpfp into place to keep the O-ring seated. This seemed to do the trick. See log below:
https://datazap.me/u/ssjneko1/log-1590080913?log=1&data=6-15-35
The STFT% was all in the negatives, which I assumed was great and EQT verified that my problem was solved. EQT sent me a new revision that upped the boost and timing and I just wanted someone to tell me how to check and see if my fuel pressure is dropping again or if this is normal considering the upped boost and timing. I didn't want to wait the 3 days or so for EQT to come back and say I have an issue, then try and fix it and wait another few days etc. See most recent log below:
https://datazap.me/u/ssjneko1/log-1590080913?log=2&data=6-15-35
I don't know if this is an issue or normal since my STFT% seems to be creeping up, but not nearly to the extent as the 1st bad log, and I don't know if I should trim some of the lpfp basket areas to get a better seat on the o-ring. Also, I'm IS38 running full E85.
