Pinging at high RPMs
Pinging at high RPMs Ever since the headers and LS6 intake install, the car won't shift until it's about to hit the rev limiter. When it does this, a pinging noise begins right at around 6000RPM during WOT, and continues until it shifts.

Have you done a good top engine cleaning lately? Couldn't hurt to try and remove any carbon buildup that could be causing it.
Seafoam or GM Top engine cleaner will do the trick.

I've done everything short of changing the wires and tune.

however my pinging started 22K miles ago when I installed those dam NGK TR55 plugs gapped at .50 was told it's too much spark power and try to lower the gap.
I think I'll go back to a stock AC Delco plug
Thanks for any good advice for the newbie
