I wonder if you are confusing VSC, Stability Control, with TC..??
 
Tc is used to assure that the loss of traction on the front wheels will not be of extended duration, so much so that loss of directional control will result. If you inadvertently use/apply too much engine torque for roadbed conditions then TC will INSTANTLY react by dethrottling the engine and applying braking, HAMMERING the brakes on the pair of wheels wherein one is slipping.
 
VSC, on the other hand, might be delayed until you get up to some minimum speed wherein YAWING can be more of a threat and/or more easily detected.

Should I ever be able to smoke the tires on dry pavement with the TC on?

If your on dry pavement, it may not activate. I suspect there needs to be a large differential in wheel speed to activate, other wise in a sharp turn it would come on. Unless one wheel breaks free, as on very slippery conditions (ice snow) it may not activate.
Mine is a 2004, doubtful there is little difference in programing between all the years.
