Its a nice day out today and figured I try a hh brisket cook with the atc. i did one other brisket over the weekend without it which temps went well just wanted to see if the guru with a 10cfm fan could get it there. after going through my logs lid temp is pretty consistently 13-18 degrees cooler than grate temp if i was to try the high heat cook and want a lid temp of 325-350 would the guru pit temp be set at 340-365(using 15 degrees for argument sake) to try to overcome the difference in temp? even if this is correct has anyone had luck using the atc to reach a lid temp in the 325-350 temp with the atc alone. using a 10CFM fan I was planning on a full ring k blue 3/4 chimney full lit minion start. top vent 100% and atc taking over to get it up there. weather is pretty nice here today 40 degrees and sunny slight breeze. I even moved the smoker to the sun.
