Deactivate AFM?

That's amazing mpg. What year is your car?

Oh and also get an alignment asap. Definitely necessary after a leveling kit.

It's a 2010. Mind you, to get that, I'm driving somewhere in the neighborhood of 63 MPH haha. If I bump it up to 73, I drop down to low to mid 18's.

Only reason I'm holding off on the alignment is the notion of me getting a 3.5 lift... which would result in yet another $79...

It's so hard to drive the 6.2 60mph. It's such a tease

oh... wow. Ummm, maybe if I had read, I'd realize why 21.5 and amazing mpg are in the same sentence. I have a 5.3 hoe. So, perhaps that changes things and explains the loss in mpg in deactivating AFM by someone else.

So we took a road trip as soon as we drove it off the lot....Ive noticed that the only time it comes on over 65mph is when coasting down a hill. At 65mph and below, it sporadically comes on if Im on a perfectly flat road that requires virtually no movement of the go peddle. It's seems really weird to me......so I think it's gonna go. On a side note, the quality on the Denali's has really nosed dive since 2007. I think I want our 07 back!!

Truck is going to be learning your driving style for a while. Drive it easy for a while then like you stole it.

Just picked up a 2013 Denali with the beloved AFM.....I have the ability to disable it, should I? Or should I just leave it alone?

Hey!

Congrats on your new Denali. Enjoy!
