Ok.... so I installed a NEW LP Sensor, and NEW 535 pump with a NEW filter/regulator on the drivers side and STILL my LPFP psi is 40-46, 5-6lbs of boost (stock) at WOT.
Can anyone tell me what to look at.

And I'm not looking for someone that needs a JB4 log to help me. Hopefully someone can figure out what I should be looking at when I have all new stuff in the tank.
