335i PANDEM KIT
I’ve attached my log here. I have a On3 single kit on my 07 335. I cannot hit target boost no matter what I do. I leak tested the car, replaced the MAC solenoid, and replaced my o2 sensors with VTT Venturi o2 bungs (so I quit burning through sensors). Any suggestions? I noticed my wastegate had play back and forth so replaced the clamp with a lot meaner one, and I have a genuine Tial wastegate instead of the on3 wastegate they provide. Help is much appreciated I have been fighting this issue for a while

335i PANDEM KIT
I noticed that my WGDC immediately drops in my log. And this is way before it reaches anywhere close to target (DWP set at 75 also).
