Welcome aboard. Many people will suggest that you try your new Bradley as-is, without any modifications, and see if it does what you want. The theme here is low and slow. Also remember if you modify your smoker it will void the warranty.
Anyhow, I like to tinker and so about 5 years ago I added a second 500W element and an Auber PID controller inside the smoke generator. For the things I smoke I probably didn't need all that but I enjoyed doing it. If you want to see how to do various things to yours you can d/l and install the two files below. They contain all kinds of recipes, mods to your smoker and a whole lot more.
