I did the first burn-in yesterday and will be cooking 4 racks of ribs today. After the burn-in, I played with the damper a bit to balance out the heat , and it seems to be near equal on the left and right side of the grill @ about 6 inches in. There is 20-25 degrees difference between the controller temperature reading and center lower grill, so a setting of 250 should give me 225 center rack---which makes sense, since most of the Yoder videos set the controller to 250----Time will tell?
