Those 9-7's are pretty nice - We never had an Aero version through the dealership when I was there, we had a customer with one - in Hawai (one of their vacation homes). I never got a look at yours at Carlisle a few years ago when you brought it with the twins. I'd imagine they move a long real nice with that LS2 - perhaps a supercharger could be in it's future? I think I may keep my eyes out for the 5.3 9-7X one day - they make supercharger kits for those too. Would make a nice towing/vacation vehicle over the 9-5.
Not too shocking. The base Vette is only 345 horse and with a sleeping driver, the 390 of the Aero makes up for it. That can be made a lot worse if you let the revs drop just for second while getting off the line.
The damned thing has a 1 to 4 "detente" and most Vette drivers who have a 6 speed buy the override kit. I never bothered since once your get used to keeping the revs a tad up you maintain a normal shift pattern.
