Im suprised nobody posted this already...pretty amazing that these issues are still going on. The Z06 forums have been complaining of this issue since the very beginning, and there has been lots of coverage in the automotive media-

Apparently the Z06 MT was testing could barely make it a lap or two around Laguna(which is a relatively short track) without going into limp mode. Pretty bad showing for the Corvette engineers...I hope they get this resolved soon, I would be pissed if I spent close to $100k on a car marketed as track capable, and couldn’t snap off a few flying laps at full power. It really is a shame, because by all accounts the car is awesome when it is working correctly.
