There's probably nothing wrong with your engine.  The smoke is unburned fuel
which comes from the G-chip running slightly rich at full throttle.  I'm not
sure if my car still does it, but I do remember it smoking a little when
mashing the throttle after I initially got the chip (version 6, I think -
I'm currently running ver 10).  A lot of cars will do this when floored,
whether chipped or not.  I'm pretty sure it has something to do with rich
mixtures having lower combustion temperatures, which is a good thing in a
high compression engine.  It probably helps avoid detonation or something
