coal black smoke rolling

I have a 99 f250 super duty powerstroke with the 7.3 in it. It is stock expect I have put a 6 postion chip on it. It was a smoke setting on the chip and it produce a little but of smoke but what can I do to make it produce more smoke?

I have a TS 6 position chip in my 02 f250 7.3 and it will throw back some black smoke, but not thick or as big of a cloud as I want. Yes I know rolling coal isn't good and that bigger injectors would help but I'm seeing if anyone knows something simpler.
