I change the heat diffuser, I lowered the feed rate, use lumberjack pellet.
First few cooks temperature went up too high, with some of the changes I did to it maintains temperature pretty much on line.
I ran into the same problem when I first went from stick to pellet... I feel you brother!!!
After many testing, pellet swap, talking to friends with pellet smoker and just reading through comments here I ended up getting "BIG D" heat diffuser.
I use lumberjack pellet for my cooks, whatever...
Overnight smoked this brisket for about 15 hrs, wrapped and finished cooking for 2 more hrs.
Very nice bark, pull and bend! Solid consistency!!
Cook at 225 all the way through, went up to 250 last two hrs after wrapped.
Anyone here smoked a brisket without wrapping? Never done it in a pellet smoker...
Also, how long will the BFG go with the hopper full to the max (how many hours smoking?)
