Not surprised at all that the thread was locked, norm for that forum to shut the Corvette owners up and protect those vendors paying the kickback fees.
This is one place where we speak the truth about slim shops like this LAPD where over the years we have seen many sick C5s that came from that shop.

They state the cause may have been bad detonation, well after seeing many C5s that were so called dyno tuned for high dollars at that shop I can tell you all the C5s I have seen from that shop had knock circuits and their error codes turned off so the customers rarely knew how bad the knock was due to ill tuning, shody work from that vendor and useless mods for big bucks that were not suited for the total makeup of that engine.
How these customers allow their cars to be tied up for weeks at that shop and suckered into even giving LAPD even more money even after their failures is clearly due to them is really beyond me.
