I cooked up three full racks on the bull this weekend, did 3-2-1 @ 180 for the first hour and 225 the rest of the time.
I did butter, brown sugar, and honey for the wrap and only a light cover of BBQ sauce for the final hour.
I put pork tenderloins on the grill for the last 90 minutes.
The tenderloins barely got touched, so that tells me the ribs were good.
I also made mac and cheese in the instapot, served with watermelon and rolls.
