Default Running Rich-rough idle with supercharger

Just wanting to pick you tuning gurus' minds for a moment. Last week the car ( 2012, 6mt, stage 2 gtm supercharger ) started running a little off, and getting progressively worse until the point where it can barely stay running at idle. I don't have a afr gauge, but I am just charging my laptop to go plug uprev into it to check. I know its rich because its giving little puffs of black at the exhaust and spraying tiny specks of soot... All last year I never had a single issue with it. I'm thinking a sticky bypass valve might be the culprit, but would a constantly venting valve cause it to run like that?

Update. I was able to actually have a peak while it was running (barely) and it looked like the bpv was closed. I'm very confused.
