Interesting, I was just about to post the same question when I saw your post.
Right now I am using my DigiQ II and Maverick 73 to smoke some baby backs. I am going to try K Kruger's preference for cooking BBs at 325 degrees.
I used the Minion method to start the fire. I have the Guru fan set at 10 CFM. Right now, after 58 minutes, The Maverick read 305 degrees and the DigiQ II reads 295. That is a 10 degree difference. Earlier when the temps were in the 250 degree range, I noticed that the Maverick was reading in the range of of 12 - 16 degrees higher than the DidiQII
