So I have my new Austin XL. Installed a fire pot heat diffuser. Still waiting for the thermometer shield. But as I understand it, if I set my P setting to P0, that would be the maximum amount of smoke? But won't it also get the hottest? I have a smaller 4.14lb Boston butt I want to smoke. I also have a 12" smoke tube I have not tried yet and I plan on adding to the pork cook. Since it's a smaller cut, would I leave the setting on smoke for the whole cook until it reaches temp? Or would P0 be an option? Or leave it at the default P4 with the smoke tube? Any suggestions?
