OK guys. I just hit 400K in my AFM motor. 2015 Denali. I'm hav'in a good time with it.Wondering how far a AFM motor can go, I'm about to turn 100k on my 2017 5.3 6L80 with disabled AFM since around 50k miles.
Anyone own or hear of really high miles on an AFM motor?
Anyone hitting 200k, 300k, etc with AFM disabled?
