My stock '06 Ram will smoke. As said previously, when babied it will load up and smoke good next time I need a little acceleration. The only time I've done it on purpose is at the on-ramp emission monitoring stations.
the worst one I had was during marathon race in town. I had a 22ft gooseneck horse trailer with two head in it. I was stopped for the racers to get across the road near the finish line. When they waved me to go through and I tried to hurry across the intersection, the truck left a nasty cloud for the runners coming down the trail. I'm sure there were folks that wanted to have me stoned but it wasn't on purpose.
