A stock X runs really rich generally. However, rich fuel trims give black smoke.
White smoke tends to be water (headgasket, or injections in heavy mixtures)
Blue-Grey smoke tends to indicate oil.
Since you're stock and you're not also saying how you feel a lack of power, it's probably just fuel from the really rich stock tune, and I bet it just looked white and grey because of the time of day or colour of your X or whatever lights might of hit it from their perspective.
Couldn't hurt to just take you're X in for a check up though.

I've had my car for 5 years now. The rich smoke from the exhaust has always been a grayish mist. I always have someone at the track come to me in the paddock to give a half assed diagnosis. I've been told everything from having a bad turbo to having a bad motor.
It just runs rich. It'll smoke with an open exhaust and especially when running leaded fuel.
It's normal.

It could be rich or it can be something else.
Honestly I would have someone check it just in case. I know it costs money but its better to be safe than sorry right?
A leakdown/compression check and if the mechanic is **** they can boroscope the cylinders and check to see everything is fine.

If you drove a subaru, and it was stock, I would think you have a bad turbo-seal too, since it used to happen with the WRXs and 04/05 STi's

Plus it'll still smoke under throttle after it's tuned unless your tuner has you all lean and mean.
Not being condescending but I'm fairly aware of what I'm doing with my use of racing fuels. My fuel trims are off and it runs pretty rich when doing so. I prefer lower 11s with track use. 1-2 gallons to an entire tank is enough to keep things happy, especially on hot days.
