It’s almost always in the 160’s.still super moist. Almost gelatinous. Literally just push on it and it falls apart and shreds itself.
I always inject pork butts. The injection depends on what style I’m doing. “American style”, regular bbq, I use pineapple and apple juice. “Mexican style”, cochinita pibil, for my wife and her family, I use a mixture of orange juice, lime juice and pineapple juice.
As a side note for everyone, if you haven’t had cochinita pibil, look it up and give it a shot. Easily the best pork and tacos I’ve ever had and it’s not even close.
