If these codes don't come back by the time my JB4 arrives, I'll have to say it was the outdated tune that caused the codes - in my case. I'll be scanning the car once in a while until the tune comes back to see if anything changes, and if so, will post.
Update: Day 4 w/o tune.....still only codes are cat-related. I'm really beginning to think the outdated tune was throwing the lean codes I initially thought were coming from unplugging the actuator. Coincidence or not, just my experience.

Update to my update (7/2) - installed JB4 Saturday, set map, did a few spirited runs to create a data log, sent it off to Terry and he came back w/a thumbs-up. This morning, my SES light was off which indicated the DPfix is back to work. And to date, since removing the JB3 2.0 chip 1 week ago, none of the reoccurring codes that I initially attributed to unplugging the actuator have returned. So, my conclusion is that I was in dire need of an upgrade and unplugging the actuator only caused the hidden code, which isn't a big deal.

335alive - You could always try removing the tune, unplug the actuator, and see what happens. Either way, I would be curious as to what codes came up. I experienced this myself and did trial/error (mainly b/c I can't let things go until I get clarification and a full understanding of what happened and why).
