Popoff plate on the stainless airbox was bent a bit. I straightened it out, and it works fine now. I discovered this after checking all of the other things which could be wrong.
Tomorrow, I fab a new plate out of 1/4 steel plate, and get some new holddown springs which will allow popoff functionality but stay closed at 6 PSI boost.

The convex shape of the popoff plate can be seen in the picture, on the right side. Bench vise and hammer got it flat again. It's always something.
