I typically wrap at about 165F-ish or so. Having said that, one of my best pork butts I ever cooked was one I put on the WSM in the morning, then forgot about it until later that night. As in I forgot I had something cooking and suddenly remembered that night, zipped out to the smoker and checked it, and WOW was it good. That's also the greatness of the WSM, nearly foolproof, and set it and forget it. Sometimes literally.
