I pulled over to check all the intercooler pipes and made sure the rotrex was still spinning. Nothing out of the ordinary. I drove the car for a moment while the SC continued to not make any boost pressure then suddenly boost pressure came back.
This made me think the bypass valve got stuck open, but iirc the pressure being built by the C38 is sufficient to hold the bypass valve closed during WOT. So I'm currently at a loss. Any ideas?

nope, never had this. were you logging at the time, curious how your afr and mafv were?
