Puff of smoke in boost
 

I tried the search button but it don't work.
I have a D15b2 tuned with crome pro, DSM 390's, RHB5(probe) stock wastegate.
I have good compression 185-190 all the way across.
When the turbo spools my friend said I get a puff of Grayish smoke out of my exhaust and then it goes away. It doesn't smell like oil and there is no oil in the charge/down pipes. It also doesn't smell like coolant and all fluid levels remain the same. The exhaust fumes smell like its running rich. My question is could gray smoke be a rich condition? Or is it oil? The top of the piston looks wet can't tell what it is though.

its probably just a little raw fuel...oil=blue

I got a video of last weekends autox but you can really see it I'll try to get some pics.
Also the plugs are a nice brown but the base is black and sooty. If it were rich wouldn't it be black?
