Dixon, did you find the autotune instructions in the Auber section? It's the same. And, how did the butt turn out? I bet your initial climb to 250 was still due to wood combustion. 190 is too high for a stepped approach to keep wood from igniting in a 3; the burner stays on way too long. Use 140 for 30-45 min, then step to 225. As an alternative, just put a little foil under the wood and start out at 225...problem solved!
