<< Can someone tell me what pinging sounds like ??
We just installed a hypertech in a buddys QC 5.9
It was made for a 5.9 (I'm not sure if it was R/T specific tho, just said
5.9 Dodge)
And under full throttle it sounds like someone is popping popcorn under the
hood or BB's rattling in a jar. Is this detonation ? FWIW - The truck does
have alot better midrange.

Yes Virginia, that's pinging. 1) run 93 octane or 94 if you can get it 2)
Hypertech probably recommends a lower temp thermostat 180' most likely,
possibly 160' 3) install a set of Autolite 3923 plugs 4) throw in a bottle of
water wetter for good measure
