Hey guys...I've done several pork butts - the last 3 were all great and finished in about 12-13 hours at 225. I have one on there now, that has been steady at 225 for 19hrs and 51 minutes, and still isn't done! The two probes are 192 and 194. At about 180F internal temp I finally got tired of waiting and foiled it to theoretically speed up the process... Still waiting. I tried tugging on the blade bone and it's def not done yet, confirmed with thermapen the probes are accurate. What gives? This is the first pork butt I've gotten from a new source...I WAS excited at the price..could it be low quality causing this or what would make it take so long?? Thanks
