GTTOOL, I guess it's stating the bleeding obvious, but the amount of smoke related to the degree of richness will depend on your tune. I don't know if you run a computer program to let you see the TP/RPM/FUEL settings throughout the performance range. If you do it might be adjustable to better optimize. Manufacturers' settings will build in a fair bit of protection by way of timing retard and increasing richness at the upper end too, to both reduce detonation risk as well as temperatures.
I don't know how some guys are launching their cars, but I maintain a fair bit of respect for my transmission and tyres, feed in mild power until I'm rolling and then let 2nd and 3rd do the big haul. This also gives the engine a chance to get the idea that it is expected to do some real work, rather than just goosing it from idle, when it is unsurprising that the ECU just dumps in heaps of fuel. Although one's attention is usually on the road ahead when straightening the right leg and concentrating on keeping the whole rig straight (especially in 3's), I do check behind and never see smoke with my tune and manner of take-off.
In any event. there are few situations when street light drags are beneficial, as you usually get pulled up at the next set and it was all a waste of time and effort.
