if not youre probably dealing with worn clutches or a messed up motor
btw have you checked to see if the basic stuff has been maintained like all the fluids and filters being changed?
The trans fluid is rated at lifetime but the reality is that it needs to be done every 25k or even as often as yearly if youre running it hard... dirty fluid or clogged filter will screw with the operation of the trans
also the engine filter might need changing - take a look at it and make sure its not clogged
furthermore you can check the throttle area and see if there is buildup
engine oil - has this been done recently? if so, did you notice sludge buildup? long service intervals will cause nasty buildups even when using synthetic oils... if someone was dumb enough to use conventional, then the buildups would occur sooner and worse
finally, if you want absolute proof the car isnt making enough power, get it dynoed and save the printout. stock those cars should be around 350 hp at the wheels
good luck

Mileage aside, an old car is just that. Since you claim to be a neophyte when it comes to mechanical things, take the car in and get it fixed. It's not a tough choice. Do it before you damage something else, if it is truly broken.
Finally, if you wanted a worry free experience you should have purchased new, with a warranty.
Good luck and keep us posted.
The Best of Corvette for Corvette Enthusiasts
OP - You wanted to try a Corvette and it cost you. Sometimes you get burned. About 15 years ago I wanted to try a BMW. About a week into ownership I hated everything about that car. So much so I traded it. POOF, 10 grand lost in a week. My lesson was learned and expensive. Now I will never buy another BMW.
Learn from this and move on. You keep bashing this car to a group of people who love them. Thats the equivalent to calling their mothers fat to their face

The dealer says no problem found. I find it hard to believe its as bad as you say it is; if the problem is so obvious - and I don't even trust dealers either.
I am not trying to be a smart ***; just let it go and get something else. Why are we still talking about it ?
If you spent nearly as much time and effort getting to the bottom of this issue rather than bleating and whining about what you see as lack in GM quality you'd have a car which can run 10.2 in the quarter by now.
You can fix the problem or fix the blame to anybody and anything but yourself.
Your call.
A less expensive approach would be to scan WOT (wide open throttle) of live data and have a good tuner review them.

Otherwise you just wasted the time of everyone that bothered to read this thread.





Other than being one of those older senior citizens who paid cash without a trade-in for a new almighty Vette that currently has 125K on the clock and one of those **** poor weak OEM (yet undamaged) A6's, I also drag race (see the performance sticky on tech & perf) and do all my own work. I'm quite sure I push my car far beyond your self imposed part throttle limitations and understand the internal workings better than many mechanics, yet I don't abuse it, nor do I whine and bltch when something wears out or breaks due to the primitive quality control.
You can't seem to follow the advice to let the dealer fix the problem, since you haven't given them a chance.
I suggest you sell the Vette for far less than you paid, then go loot and burn down the local CVS to resolve your frustrations. Next go buy a used foreign car with a V6 that was likely made in the US and get on their forum to do your complaining.
