I'm a bit conflicted about AFM . It is very dependent upon your driving style and load whether it is active . I drive the truck normally
95% of the time , but from time to time like to open the throttle and feel that V8 pull . On the highway trips , I don't mind
the V4 activation as long as it isn't causing undue wear on the components and that it is actually saving gas .
I'm trying to be confident with the evolution of these engines over the last several years that they've eliminated most issues ,
but the ticking I get at cold idle (post in another thread) has me cautious .
I live in the mountains of W NC and have driven many of the roads here which is fun , but I don't care for the AFM
coming on during those times .
I thought about one of the AFM disabler , but if I'm going to apply the money towards one , why not apply that
to a tuner so I can approach the transmission constantly trying to find the right gear or lugging as well ?
What I'd like is to have economy when I want it . I just wish GM had given us the option .
So hopefully a tuner will help with that once warranty is out . It's hard not pulling the trigger now .
