I’m smoking a pork butt now at 220 degrees should I smoke it for the entire cooking time or take it out and put it in the oven for a couple hours to finish it

I smoked bacon today after curing it for five days. The taste was great. One problem is it’s tough. I tried following the directions hour by hour, but a couple times I wasn’t watching the temperature and it was off about 15 degrees too high. I tried to compensate for the next time period. I couldn’t find my thermometer, so I didn’t know what the final temperature was. Do you have any comments? that might help next time. As I said the taste is great just tough
