Black Widow Pkg ?
That must be an upfitter or after market thing ? From a vendor GM has authorized to modify the vehicles ?

GM and Ford, probably Ram too, authorize aftermarket upfitters to provide an alternative to what the factory offers..think back to the conversion van craziness of the late 70s through the 80's and 90s.
Way back when, as in pre-Expedition, Excursion era, Centurion would take a Crew Cab Ford, cut some of the frame off and install the rear guts from a Bronco....what could possibly go wrong?
I'm not going into the politics, as a dealer you either loved them or hated them...I hated them, my opinion being the manufacturer was taking allocation from the dealers a who needed it and instead was giving it to the "pool" companies, who would charge the dealers 10-12k for a wheels/tires/lift/paint package we could do for half that...but if the dealers did it, and the vehicle was ever involved in an accident and lawsuit, GM would waste no time in telling the dealer "sorry, no indemnification for you, you modified the vehicle beyond it's intended purpose"...I'm sure no $$ changed hands for the upfitter to obtain authorization for their modifications. Again, in my opinion, they're taking what needs to be custom work and trying to do it in mass quantities. We had a customer of ours who convinced himself he couldn't live another day without a new GMC at a dealer down the street; the truck had a ton of eyeball, and also had a blower performance package. It ran like ****, the dealer who sold it to him couldn't get it to run right so he brought it to us...long story short the motor was way fat so the general public would be less likely to hurt it and have a warranty claim...we dx'd it, but wouldn't touch it and advised him to go back to the dealer he got it from and get the company who installed it to tune it correctly...the minute we touched it he'd be out of warranty. I think he ended up in a lawsuit and the dealer ended up buying the truck back. Anyway, I'm not a fan...
To be fair, I think there probably a few custom shops who are capable of not doing hack jobs ...Roush comes to mind, and there probably are others...we used to have a sign in our pit that said "Good. Fast. Cheap. Pick Two."
RE 6.2 and lifters -
We've seen some issues, but we also have several out there with no issues and the people who haven't had issues ran exclusively premium fuel...I'm unaware if that has anything to do with it, just an observation.

That is what he said - very hit and miss.
I bought a 19 Denali new w 6.2- only run 91 and so far so good. pushing 80K miles so far. Chit for milage tho lol - best is around 15 and i check if almost every fill up.
But I drive the hell out of it.
Now if they would tell me why the damn "Trailer Brake System" warning comes on sporadically- it would be nice. Time for service so hopefully they know what and it has happened to others.
Sorry- kind of deviated from 6.6
