What octane fuel are you tuned for? If less than 93, you could try putting a higher octane in and see if it goes away. If it does, yes you will need a retune or use a higher grade of fuel.

i am tuned for 93 and have always used 93.... the only time my truck had anything less was the day i drove it out of the dealership
(cause i doubt they filled it up with premium) lol

im thinkin the same thing. thats what it sound slike anyways. Do you buy fruel from the same place every tiem by chance?

myabe the guy has your timing off and your not putting enough octane in it,

unless im out of town. It doesnt ping all the time though, it does it sometimes. on the same tank of fuel

Pull plugs, check them, esp the driver side.. Sounds like PING to me

hmmm.... ok, check this out. About 6 months ago or so, i had a local POS shop install my converter. They lowered the tranny, but had to unbolt the headers and cut my Y pipe. Guy did messy *** work, cut one of my tranny lines.
When i brought it back home, it was misfiring, So i started pulling out my cables and found a spark plug completely shattered. Changed that plug and 1 more that the ceramic looked cracked. But i didnt check the rest. Could a cracked spark plug cause the pinging im hearing?

It could, but if the plug was cracked, wasn't sparking you would have a ses light on.. easy way to find out is to go check all them then...
