What happens when run w/o a boost controller with the wastegate directly to a pressure source?

Without an MBC, BCS, or some sort of boost management, the boost will go up and wont stop.

yeah, I am not saying that. I am saying I had a joe p on there and then I switched to the dual stage and now I have switched back to the joe p and it overboost. but.. when I had the dual stage it still over boost like that. But I figured out. thanks

I read that the wastegate will open at 8 or 9 psi if its hooked directly to a boost source.
