I was on the highway one day driving my 06 ss s/c and hit the rev limiter and my car shut off. I turned it back on right away and i noticed that the tone had changed overall and it was deeper and quiet. The supercharger sounds sort of different now too and theres a whistle when i hit boost. after it shut off it began to misfire so later i changed spark plugs and that problem stopped but it still sounds weird and it feels like it lost a little bit of power. Any ideas as to what happened or what could be wrong? thanks.

I would suggest you continue to discuss this in your original post.

Open the valve cover and check rockers and lifters
