C207 E400 Smoke?

I have the 3.0 turbo, and noticed that when I mash on the accelerator(full throttle) that I get a big puff of smoke. Then It starts to simmer down after more full throttle spurts, to the point that I don't notice it. Maybe after three times. The smoke is kind of a white color, but not pure white. I just changed the plugs and the old ones looked good. There is no oil or coolant leaks or smells. The car is fully warmed up too. I am baffled.

I did notice a little bit of oil in the passenger side intake tube(in front of the turbo) when I changed the plugs, just thought that it was nothing though.
