use wood chuncks and you will get ur smoke flavor. It's not necessarily the cooker it's more of the pellets. That was my major complain at first also. I threw in a wood chunck and had great smoke flavor. Wood chips will also work but they burn faster.
I use pellet to start my fires with wood I lite them in the smoker box and dump them in a basket at the bottom of the cooking chamber then throw a wood chunk on top just make sure the grease doesn't drip onto the fire trust me she will catch fire.
I like using the basket at the bottom because it really feels the chamber evenly with smoke where the smoker box is too high but it will also work just fine for wood chunks.
