I've been playing with my Yoder with the diffuser plate in since I got it. I smoked up a 8 lb bone in Boston butt to make some shredded pork couple weeks ago and with the diffuser in it seems to take a larger fire and more fuel overall. Smoked a tri tip last nite without the diffuser and used very little fuel compared to before, I'm currently smoking a 10 lb boneless Boston butt today and keeping a constant 235f in the smoker with half the fuel I've needed in the past. Has anyone else noticed this using the diffuser plate??? The way it's designed it seems to block almost half of the top inlet from the fire box to the smoke box restricting heat into the smoke box. Also I've looked around and can't seem to find a Yoder group?
