I have been searching for mods for my pittmaster deluxe to make it more efficient, and I am having a hard time finding info on mods. I have heard lowering down the smoke stack will help as well as putting in a baffle near the fire box. I am looking for some simple mods to improve the efficiency of my smoker but I don't want to put a lot of money in it and do not want to completely rebuild it either. Any info will be appreciated!!!
