Engine Drag Contron
While trying to beat the light in a left hand turn, I down shifted pretty hard, and all of the sudden the vette just accelerated for a split second and the Message "Engine Drag Control" came up on the DIC.
Is this Normal?

Proper downshifting requires rev matching; blip the throttle with the clutch down so that the engine revs match the RPM for the gear you are downshifting into; this will make your downshifts much smoother and prevent this problem from re-occuring.
As patton said; the car's behavior was normal, but your driving wasn't. In a lesser car without engine drag control you would have wrecked.

You made a bad driving mistake; your downshift during the turn caused the wheels to decelerate more than you had traction for, effectively doing what would happen if you had pulled the handbrake mid turn. Your car's wheel speed sensors detected that and the driving aid nanny stepped in and accelerated the engine to prevent rear wheel lockup which would have you spinning out of that turn out of control.

i'd downshift in a turn in lieu of popping the clutch to initiate a drift, like around a rotary, or after ordering from the menu at mcdonalds and turning left to pull up to the drive-thru window 
Of course those days are over and none of this applies to the vette.

Of course, making 518foot pounds of torque at the rear wheels helps

I've gotten this message in the same location a couple of times - while having the engine decelerate the car going downhill on an overpass - never saw the message anywhere else.
