I took the car to Bavarian Motorsport and had a second smoke test. Found the throttle body to ICV hose leaked (at both ends and the elbow), and the brake booster vacuum elbows also leaked. All of these elbows are just pressure fit. Here’s what I did:
I hate the way the hose clamps look but they’re necessary. So this worked great yesterday, but last night the car bogged after sitting for 2 hours. Now I wonder if the RTV sealant isn’t up to the heat of the operating engine.
Seems I forgot to tighten the hose clamps on the intake boot. Running better now!
