Most miles with stock AFM system?

On my 2006 Saab, they lasted to 161911 before the lifter on cylinder 1 died. I replaced only the lifters on that cylinder, and its still going with its now new owner.

Around 101k with my 2019 Suburban, BB tuned and AFM still working no
Issues… but might get it disabled through the tune soon.

149,000 on a 2015 suburban and still runs Ike brand new.

Just an FYI. In our experience and feedback from customers, most issues the AFM system causes occur with the 2007-2013 models. They still occur with the 2014+ models but not as frequently. Most of our customers with 2014+ models still decide to disable the AFM anyway just to be safe.

Do you guys keep track of how many AFM delete tunes you have sold for the triplets? 10K? Just curious as I'm guessing 95% or more of the millions out there have no idea what a AFM delete even is.

I read a lot about deactivating the stock AFM system because of the many reports of trouble. But I often wonder who has accumulated the most trouble-free miles while running the OEM system. I have 114,000 on my '16 Tahoe, and no trouble yet (fingers still crossed).

I've seen posts of 200K+ miles on a stock tune. My guess is that 95% of the triplet owners have no idea what AFM is, much less how to delete it. I am also guessing there are a million or more out there with at least 100K miles and no issues.....

2007 Tahoe 5.3L bone stock 275,000 miles, no problems, added catch can at 220k, drive it like I stole it, regular maintenance with good oil and oem parts, loses about a quart between oil changes, I guess I got the unicorn

My 2010 Yukon XL Denali was at 182K until I got my blackbear tune a month ago. Mostly highway miles, no towing.

2015. 267,464 miles. Nothing altered. First 220k were gentle miles , always warmed up and driven steady state at 55 mph ish. Moved to Florida and regularly see 80 plus on I 75. Oil changes about every 7k with quality oil. Pulled the valve cover earlier this year, was spotless

My 2009 5.3 Tahoe went 210k mile before the AFM lifters went. Happen on a road trip 4 hours away from home. I chose to drive it home in that condition. Motor was toast when I got home.
Bought a 2013 LTZ with 113k on it and immediately plugged a Range Disabler into it.

We don't keep track of that exact stat but the number of tunes we have completed where we disabled the AFM is in the thousands.
