This is driving me nuts!! I have never had a piece of meat cook anywhere near 1 1/2 hrs per pound on my UDS. My temps are 250* solid and since I kind of know the rate my drum cooks I put my 7 lb butt on at 8am thinking an hour rest gives you a eat time at kick off tonight.. I am now foiled and sitting at 197*. I replaced the temp probe once already and tested it in boiling water to make sure its correct. I just now added my baby backs so my butt is looking close to being done yet the ribs are 5 hrs away from done. Why does my cooker ALWAYS cook faster than 1 1/2 hrs per lb at 250*
