at this point it looks like this is a known issue with the canned #2 tune, not a couple coincidences. Good thing I found this, I was just about to start throwing parts like coilpacks at it to solve the issue.
I guess its time for a ticket for me then. btw...2006 fx4. is it just me or is this a lot of 06 models?

I have an 06 aswell. But I am getting the problem on all settings. I seem to get it more often in towing and performance setting then economy so I just leave it there and deal with it. However when you have an 8 foot camper on your truck and your climbing 2 miles of 12% grade and the problem happens you pretty much have to pull over. I have noticed that if you turn the engine off and start it back up, it (the problem) instantly goes away.
