99 torch red vette

I have had my vette for about 9 months now, and seems to be detonating at the track and high RPMs, I have changed the fuel filter, decarbed the motor, but no luck, I also checked for any leaks between the MAF the the TB but no luck, it even does it when the motor is cool or warm.
my mods are in my sig.
thanks for any help

I had my knock sensors replaced in my coupe. But that was for a knock problem.

so did that stop you knocking at high rpm?

There have been service bulletins issued for 99's with knock problems. If you are using the factory PCM calibration, have your dealer read the CVN number that is programmed in your PCM. He can then check to see if you need to have your PCM reflashed to the latest revision. I have read that this is not covered under warranty and it cost about $90 to have the unit reflashed. Don't know if that is accurate or not.

It fixed it.
