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.

2008 went bust at 124,300 miles changed the oil every 4500 miles since i bought it at 84k

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.

My 2016 Tahoe just turned 165K miles. 100% stock no issues. I know I should get it tuned but do not trust any shops here in Florida,NYC or New Jersey to tune out the AFM. Do not want to hook up the Range.

Still runs like brand new. Still using 0w20. Change out every 5K miles with either Mobil 1 EP or AC Delco.

@BlackBearPerf Now if they came anywhere near my neck of the woods or in NYC-N.J. I would let them tune it.

Curious why you don't want to use the Range?

Since it is still running like brand new [180K miles] do not want to do anything with it. Not even a Range. Gets serviced every 5K miles. Eventually I will probably end up getting a tune when I move back to Queens NY.
