Since the question of cook times comes up quite often, I thought I'd post the data from the pork shoulder that I cooked today. It should be stressed that cook times should be based on internal temperature of the meat measured with a good temperature probe, but this should at least give everyone some useful data on approximate cook times so as to get a general idea on when to start cooking. Reference the chart below for what temperatures to expect during the cooking process. Note the "BBQ stall" between hours 8 and 14.
After the meat reached an internal temp of 180F, I bumped the Smokin' Tex temp to 250F to give the meat a little better bark. I injected the roast 6 hours prior to the cook start time. At no time during the cook process did I open the door for any reason. After roasting I wrapped the roast in a double layer of aluminum foil and placed the roast inside a cooler with some towels placed on top to rest for 2 hours prior to pulling.
