Pinging isn't a good thing and can never be considered "normal".
What about the knock sensor - that's what it's supposed to do, retard timing to prevent pinging.

I know. Knocking is bad. According to the tech, my knock sensor works fine. And my computer works fine as well; pinging occurred at the same spot both with the stock PCM and the Stage 1 PCM. Still, after dropping my car off for a day at that 5-Star Chrysler dealership THREE TIMES, I just had enough. It aggravates me too much to know in advance that I'll get back there and they claim there is no problem. Or that the tech will acknowledge the problem and then never get back to me. Maybe I'll get the PPQ and see if I can tune the PCM myself to get rid of the knock.
And maybe I should take another look at the plugs. I replaced them with Iridiums which cut down the pinging a bit, but it's still there.
