Went back to all stock. Low pressure looked good. Slowly started adding things back. My low side pressure is always good now. Now I got high side issues. At idle, I am seeing about 600 and 1000-1200 is desired. If I go to 2500 rpm, my rail pressure and desired rail pressure equal out and it runs smooth. I am burned out and calling it a day. I'm starting to regret modding the car. Lots of money and doesn't seem to good right now. Hopefully, tuner can see something that I am missing.
