The slowest of the C6's, the 05 LS2, goes 12.4@114/115 on stock tires. That's not magazine numbers either, that's a lot of people doing it.
Even on the older LS2 ones, they really wake up with only a catback and a tune.
If he has decent tires (as we already know he does), it is completely believable.
