It may be a combination of both heavier fuel delivery and the additive. Run the additive out, and if it still smokes, then turn down the fuel.

As for more smoke of course any adjustment to fuel delivery could change the amount of smoke. If you had guages and your EGT's were higher than that would definetly tell you if you were pushing too much fuel.

Sounds like you are getting to much fuel. Seems as timing is fine if everything is responsive and idles well. But with a haze sounds like it is dumping alot of fuel. If you lug it down in a gear do you get alot more smoke than you used to?
