the wrong spot.
I was going to replace the diaphram. I'm guessing if it is stuck open a little, it could be allowing exhaust gas in all the time and it could be allowing boost out the manifold.
I do have a EGR delete, but wanted to keep the system intact.
Good luck Rob! I need some luck too.

What you are seeing is most likely from back pressure. My tubes kept poping off also it stopped when I took the cats off. Cats were almost plugged shut!
