They had no plans to keep it stock, and that should not surprise you.
When the video emerged not long ago of a Corvette Z06 with one mile on the clock doing a burnout in front of the dealership, it had a lot of people up in arms. Never mind the fact that the burnout was done at about 2,000 rpms doing about as much damage to the engine as driving to the grocery store, people got really mad. Well, it seems that the car has already been modified to make more power, and more is likely on the way.
The car was put on the dyno (definitely more damaging than the burnout) and there were some noticeable gains. We look forward to seeing what else will be done to it.
