Good tips. I'm going to look into cleaning the bypass passages, as the air screws don't seem to change things much.
Also noted this warning in the C-M-A document. Giving this a bit of thought, as while I did add about 6 gallons of 87 the other day, I don't know what fuel the seller put in prior to shipping the car to me. I wonder if this is really a significant possibility, especially in combination with the slightly colder plugs. I think I'll pick up a set of BPR6ES-6 later today.
