Adding my experience to Mr. Minion's (guess who has more?? HINT: it's not me!!), YOU MUST resist the temptation to pull it off any sooner than 195? internal!! It's hard sometimes, like when you've been cooking since 4am and it's now 8pm and you want to have your fill of pulled pork (I'm describing me last night....) It's worth it though.
My recipe: whatever rub you have bought or concocted yourself (mine is 5 parts brown sugar, 3 parts kosher salt, 2 parts paprika, 1 part made up of chili pwdr, garlic pwdr, onion pwdr, black pepper), and run the temp between 230-250? until it's done (see above.) Let it rest wrapped in foil for an hour or two, then pull apart and eat (careful, probably will still be pretty hot in the middle.)
Hmmm, I think I'll have some PP leftovers for dinner now that you have me thinking about it!
