After sitting at a stop light for a minute, I get a big poof of smoke upon acceleration. It has done this since I bought the car about 1 month ago. Would this be related to an oil leak in the turbo system?

I definitely feel turbo boost, and the engine feels strong, but I don't like the extraordinary amount of smoke coming out of the tailpipe.

Have recently had fuel lines changed (running b100 now), new fuel filters, new air filter, valve adjustment, new style breather hose. None of these has affected the smoke. Could it be an oil leak into the turbo that upon spinning up at acceleration blows out a puff of light grey smoke?
