I cooked on my PBX for the first time today. Temp was out of control. I put the big meats on at 275f, and it quickly spiked to 350f. It got up between 400-450f for a large portion of the cook. What did I do wrong, or what can I do differently? Filled up the pan with Kingsford blue bag, and added 1 full chimey (Pit Barrel brand) of lit charcoal after burning down for 12 minutes.
