HELP! Conflicting temps!

[CJ Eichinger]

15 hours into my cook (7 lb. butt), the Guru says the meat is 202 (several locations), but my cheap-o Taylor digital pen says 187! I am not in a position to calibrate the Guru (mid-cook), so I took the Taylor and put it in a pot of boiling water, where it read 212.5 degrees.

Should I assume the pen is right and not trust the Guru meat thermometer for this cook?

Thanks!!!

Go with the pen as far as temp, but I would go by feel at this point! If tender pull it and wrap it.

Go by feel, probe the meat in a few areas with our pen probe and if it goes in real easy its done or if your butt has a bone in it and you can pull it out real easy your butt is done.
