The primary reason that many people wrap pork butts is to shorten the cooking time. Due to the amount of moisture in the meat, once the butt reaches the stall, it can take quite a while for enough moisture to evaporate so that the internal temperature starts to rise again.
You have three options:
1. Leave the temperature around 225 F for the entire cook and just wait out the stall. It will eventually get there, but could take a while.
2. Leave the temperature around 225F until it hits the stall and then boost the temperature up to 275 F to power through the stall.
3. When you reach the stall, wrap the butt in foil or butcher paper and put it back on the grill. You can either leave it at 225F or boost the temperature to 250-275F if you are in a hurry to get dinner on the table.
Whichever way you chose, when the pork reaches its final temperature, wrap it in foil, wrap the foil in a towel and place it in an insulated container for an hour or longer to let it rest so the juices can redistribute throughout the meat. thus, always plan for the cook to finish well before dinner time.
