After doing this experiment I am not sure boost was getting past the valve, I am thinking putting this portion back to stock and putting the valve cover breather to the catch can.
The seal on the bottom of the cap is a hard rubber almost felt feeling pad on the bottom of the cap. Me over tightening he cap is using the threads compressed to seal rather than the rubber alone.
I left that alone. That line goes in between the VAM and Turbo. I am contemplating running that line to the catch can in place of the crankcase vent as I have it set now.
