Federal smog laws GregO'Connor

Would a waste gate turbocharger help reduce the smoking? A previous owner installed one on my coach -- and I've noticed very little, if any, smoking from my S-60. I presume that the waste gate turbo is set to spin up faster, then the waste gate opens to stop any over-boost (maximum I ever see on the gauge is 25 psi) as it achieves maximum speed. While certainly not cheap, it might be a solution to consider, especially since it probably gives a horsepower boost at lower RPM as well as cleaner burning (possibly offering a slight MPG improvement). However, I have no experience without the waste gate turbo so I don't know what effect it may have had.

The only time I see serious smoking from my S-60 is when starting with the engine very cold (but using the engine pre-heat solves that, as well). Indeed, now I run the engine pre-heat for 30 to 120 minutes whenever the ambient temperatures drop below 50 degrees during the night (for a morning start). The colder it gets, the longer I run the pre-heat. 

I note that I get very significant smoking from the generator whenever the air filter needs replacement -- but a clean filter eliminates the smoking.

I have experimented with letting the turbo spool up a bit before I hit the accelerator hard. I noticed that my black smoke is somewhat less when I do that. Of course, to the consternation of vehicles behind me, my slow forward progress is not what they were looking for.
