Actually, if you tune for max power, you will get a lot of smoke on a diesel. Some of these morons may over-do it, but if you look at a pro diesel drag race or pulling competitions with diesel, you will see what a max tune produces in terms of smoke ... I am not sure if it is done for best mixture only or for added cooling etc.
