I have done it with chicken legs, I smoked for a while not sure how long, I do remember the temps were 160ish when I took them out, then finished them in the AF at 385-400.
Have also done it with country style ribs cut from Butt. They come out nice the fats and outside crisp up nice with the sugar in the rubs.
In the same area, I will smoke CS ribs or chunks of chuck roast for a bit and finish in the instant pot. If I am going to do that I will usually smoke in a pan so I have the juices for in the pot to build pressure.
