The 180 setting usually averages about 200 per the meater probe. After putting it in the boat, bump it to 225. That usually produces about a 265 average.
My larger Traeger I use for brisket is a Costco $700 version of the old L’il Tex elite. The Costco version had a lower cabinet on it. Probably have had it close to 10 yrs. I’m sure the new ones are better at maintaining a consistent set temp.
I’ve had better results pulling when the meater internal reads 195. If I go over 200 (like the last time), it starts getting a little dry.
To rest it, I wrap with foil, then towels and put in a cooler for a few hours.
Here are a couple pics from the last one. As said, I pulled it a little late. It was definite on the dryer side.
