The bypass won't release because of pressure. It'* not like a blow-off valve.
Most of us are using aftermarcket PCM'* that have programming changes to optimize the control of this safety feature to allow slightly higher pressures.
I admit that I once used this technique before I replaced my computer.
It'* simple to do. If you do a search on the topic it should explain everything.
I don't recommend it.

it is not like i have only 1 car and engine. i have two l67'* setting on engine stands and i know where i could get 1 or 2 more. i'm just trying to perform and brainstorm. trial and error is the only mothod that has ever worked for me. just like to know as much as i can before a trial turns into an error. how does the boost control solenoid work?

It'* told by an electrical signal via the PCM to either turn vacuum on or off to the BCS.
Rather than trial and error on this one, I suggest you learn from our knowledge and mistakes. Don't mess with the BCA or BCS.
In addition, you can't get 20psi out of a roots blower, and most of what you're talking about in this topic is going to require EXTENSIVE work to that engine and trans to support it.
I just want to make this as clear as possible, as it sounds like you're ready to move on some of these ideas.
