P0343 code
I recently had my 04 Z16 ZO6 supercharged with a T Trim @ 12 PSI (stock engine / cam), and after 5 months of easy driving, I got the dreaded P0343 code. I searched, and multiple threads pointed to loose cam bolts...
Well, sure enough, that is what the problem was. My mechanic replaced the stock cam bolts with ARP bolts, locktited them down, and code was gone. The cam was physically loose, so it was a ticking time bomb.
Oh, and if you think that this only can happen after repeated pulls on a stock motor, think again. Not including the dyno pulls, which happened in the winter time, I probably made a total of 5 WOT pulls, in 5-6 months. I drive like a grandma most of the time. Believe it or not, it is my daily driver, at least for now. I just really would prefer not to have 3 cars in the family, but may be forced to do that with the new setup, and potential future downtime.
Just wanted to post this to anyone seeing this code - take care of it ASAP!

Thanks!
While it was in my mechanic's hands, I had him strengthen the rear end (output shafts, DTE brace, new seals, etc), and had him install the Alky Control Dual Nozzle meth kit. Going to get it retuned shortly.
