Ok so here is my question which came from a talk between a well ranked diesel truck puller and myself. I am running a custom tuned 06 w EFILive from a well know tuner on the forum. My tune is very very clean and lots of power and I am VERY please with his work. The puller seen the video and was saying I have minimal smoke. I know more smoke means more fuel, more fuel allows for more of the air/oxygen to be burn't in combustion, hence making my power. So not from a environmental perspective, is there more HP just not as clean, and the clean tuning more for the street and sort of a compromise of HP and cop friendly? I am not asking about cool poitns of rolling smoke. I am just wondering will a clean tune make as much HP as one where you added additional fuel
