At first they all cook a little hotter but after about 5 cooks it stops cooking so hot. This is for any WSM.
In regard to temp controllers, there are a few threads on this but I use Auber controllers. IMO they are a cost effective way to give you peace of mind about temp control if that's what you want.
Bob must ask you this: did you ever test 250F cooking T?
If yes wich differences did you notice?
Much better for pork (ribs or/and pork butt) or beef (brisket or/and shorts) ?
Bruno with my set up (waterpan removed, pizza stone installed, CB door, ATC installed) my WSMs run like champs super steady at 250F, exactly where I want.
Hi Enrico... At Harry's suggestion, I moved up from 250 to 275. It seemed to do a much better job at fully rendering the fat, in pork ribs, pork butt and beef brisket. At times, have played around at 300 with good results.
