I mentioned your post to my wife, and her comment was why do you want to make smoke, as I am trying to not make smoke.

So, I am assuming that you think if it does not make smoke it must not be putting enough fuel in. If the goal is to make smoke then you are not putting enough fuel in. However if the goal is to make more power(I am reasonablily sure it is) then smoke is only an indicator that you have more then enough.

Are you making more power, and are you happy with the power level now? If so then be happy you are not making smoke. I still say you must check your fuel pressure, then if more power then you have now is the goal there are more things you can do.
