Gotcha, from responses; using some lubeguard on this engine may be a good idea sound or no sound so going to start that up. On 2nd tank of 93 octane as of this morning along with the 2nd round of Lucas fuel system cleaner see if that helps. I did notice a bit better throttle response after about half a tank first go.I'm not confident yet in saying if/what has been fixed. I will say that in the few years I've been running my truck, 91 octane consistently has the least amount of ping over 87, but it doesn't remove it completely.
Recently I ended up buying different gas and also did an oil change to 5w-20 (down from 5w-30). It's HPL oil in there now, it was before as well but it's a different formula too; so went from HPL euro no vii 5w-30 down to HPL regular 5w-20. That weekend I did the oil change might have also coincided with a change from summer gas to winter gas.
After that point I towed the next day and the pinging was the least I've ever heard that I can remember. It was almost non existant, just a tiny hint once or twice.
Since then I've been driving very conservatively, keeping rpms low because my diff is making noises and I don't want to stress that out until I can swap the diff oil (hopefully this weekend).
So who knows, too many variables changed at once, might have been a fluke with the gas but at this point I do suspect the oil was the reason because I've gone through several gas changes (winter/summer) and also different gas stations and octanes etc, trying to see what works and nothing has until the weekend I happened to run the 5w-20. I just don't want to make that claim yet though without more time and testing on different gas etc, I've been wrong before
