Under full throttle and heavy load, the car dumps alot of extra fuel into the cylinders. This is why most cars will puff some black smoke when accelerating hard. It's normal. If it's blue smoke, it's a different story.
Great, explaination, but, what if I see...say...green smoke? Should I call Ghostbusters!!!

Boooooo. Happy Holloween!
