So this would be my first shoulder in my master built duel fuel. Bought a 9 lb shoulder, trimmed, and rubbed yesterday. I tossed her in the ol' smoker today at 6 pm expecting 1.5-2 hrs per pound. I'm Having family over tomorrow at noon. I'm a little concerned it's cooking too fast and will be finished way too early. The pork went from an IT temp 37 degrees to 124 in 2 hrs 15mins at a 230 BBQ temp. Does this sound about right and it will slow down? Or did I put it in way too early and it will be done way too soon?
