What does this #8 "cackle" sound like...
I recently purchased an 03 with a 7.3 and about 130k on it. Truck is in good shape, and I feel like I got a good deal on it.
Anyway, It sometimes has a noise to it like a gas motor that is pinging. The sound goes away if coasting with the TC locked (injectors 'off'). The noise seems to come from right in front of my knees.
Is this the #8 'cackle' that I have read about, or do I have other problems? This is my first 7.3 and so I'm still trying to figure out what is 'normal'. The noise gets more pronounced with the tuner on anything hotter than stock.
Thanks for the input.
Also, is this something that the rifraff regulated return would fix/reduce?
I can't imagine we'd be welcome at hooters very long if there was a bunch of half drunk guys in the back sitting around whistling and humming trying to make the perfect 7.3 turbo noise...
