I did a lot of research on the issue and it seems very reasonable to believe the engine is receiving unwanted air from somewhere and the likelihood of a leak is high. Some have said they used a smoke test to find leaks...I've never done that, but it can't be that hard. One person posted that they found the lid to the SC loose allowing extra air.

The idle is approximately what it was before. But, when warmed up and in gear like at a stop light it doesn't seem to idle as smoothly as before.

It's been 10 days now and I still haven't had contact from Edelbrock on the issue...at least not from the supercharger tech. I am patient and expect they are pretty much swamped, but....
