He drove both cars in the same way so it seems to me the test was fair as getting those numbers he got.

I would say that is not correct. The rear weight bias of the rear engine platform is an advantage when you have sloppy/terrible technique shifting. The launch control also helped the GT2 alot. You have less of a margin for error to get the best possible times for the traction limited Z06. The GT2 is faster....just not by the ridiculous margin shown.
