Most miles with stock AFM system?

[Marky Dissod]

Does a person have to pull the heads to do an Engine Half@$$ delete, and if so, why?

Could swear there's some sort of trick, where you spin the crank slowly, which lifts individual lifters as they ride different cam lobes,
and you can pull them out one or two at a time - but I've never done it myself so don't quote me, please.

My brothers 09 Tahoe just passed 205k with stock AFM running. I don’t think he owns a wrench but he does get it regularly maintained at a private garage. He bought it with a 100k on it.
