I dont think he is useing it for pulled pork if he is pulling @ 170 IT. BDGE, try 200 IT for pulling or something in between, maybe185 if your loking for slices. We like our roasts falling apart so I usually go for 200 IT.
I would recommend doing a well documented common cook on this site, i.e. ribs, pork butt or brisket. Follow procedures from beginning (brine, rest, rub, rest, cook, rest, eat). Once you do this you will get a great idea what these can do. It will make it easier to adapt to the more uncommon cooks.
Your going to love it once you get dialed in. Also, no need to soak your wood chunks. Good luck & hit us up with any other questions.
