On the level 3 setting ( switch on the fly with a toggle switch) it will definatley smoke those rice rockets, but will not produce the black smoke you say you want. As far as I know, this switch on the fly feature of most chips is not possible with programers. I'm sure you are aware that the black smoke comes from excessive fuel dumped in the chamber and not burned.
There are several good products out there and if you do decide on a programmer the Bullydog seems fairly popular with the GM guys. BTW, apparantly none of the newer programers or chips increase pressure (that was the very first generation stuff).
I may not say this when it comes time for a major repair, but for now I can say I will never own a gasser truck again--- I love that freight train power and fuel economy.
