Also, how accurate is your thermometer?
Maverick ET-732. Pretty accurate. I was also cooking with three full pans (2 butts per foil pan, and one for the brisket). I think that may have affected some air-flow.
The brisket was in the 150 range while the butt was a good bit lower. One thing to note is that the 133* was after changing probe placement, and it came up to 144 pretty quickly so I'm wondering how much of it was lag-time on the probe coming back to temp.
Brisket is sitting at 156 while butt is 144. Maybe I will do a couple spot checks on the other butts with the thermopen.
