Wrapping it in foil you won't get the crusty surface, aka bark. For a while I would let the internal temp reach 180F before I wrapped. Soft bark, but better than wrapping at the stall. Now I don't wrap at all.
203F-207F is generally the range for pulled pork. I do prefer mine at 201F, but I don't wrap in foil at all so that the fat can render free. I do get a crispy bark.
Next time, try not wrapping. Set the smoker at 225-250F and walk away for at least an hour per pound. No looking, no peeking, no worries. If you have a wireless thermometer, like a Maverick, you can insert the meat probe after the hour per pound. If you are just using a meat thermometer, check the internal temp of the meat. It should be around the end of the stall, high 160s to 170sF. You can crank the chamber temp up now to 275-300F, figuring 6-10 degrees internal temp per hour until finished.
I prefer the bite at 201F. I don't like mushy pulled pork, and haven't come across it yet at 201F. I have had mushy at slightly higher temps.
Hurry up and eat this one so you can do another!
