last night I smoked 2 pork loins on my masterbuilt. one turned out really well and one turned out not so good. I made a homemade rub and put it in the fridge for 2 hours before smoking. smoked it on 250 for 2 and 1/2 hours and one turned out really dry and one turned out really juicy and tender. I dont know where i went wrong. the internal temp was 170. any suggestions? Thanks
