Needs to know for Afm Delete

[Blksilverado31]

Looking for a basic needs to know for what to expect and what i need to do following the delete.  I could not find much so if anyone could point me in the right direction would be greatly appreciated

Range device would be my choice.

I have one.

A tuner if you want to play.

If I'm not mistaken you can do the afm delete with your tuner...? No need for both.

Nothing. Just drive it like you stole it.

at least ill have the chance to do that now.  Thank you  just wanted to make sure

You can expect lower gas mileage.... lol

Already there now. What’s a little more

I average better mpg without afm. Afm is a joke

just because you turn off AFM doesn't mean you still won't see issues with the AFM equipment in the engine.

But it has to reduce the chances significantly, right?  I'm not engine mechanic but the folks who ARE and chime in on this topic sure seem confident it reduces the chances.......

I'm not an engineer but believe disabling AFM stops the special lifters on the deactivated cylinders from going into AFM mode.

I think this would help with durability.

A motor has hundreds of moving parts. Some roll some turn some slide some articulate some oscillate. What exactly is it about those exact same movements in an AFM assembly that spells disaster for them in some unique way?  Ever hear of Rhoads Lifters? 

GM uses a solenoid to do what James Rhoads did with bleed orifice size to gain more control. The original VVT VVL system.  Maybe we should go back to solid tappet systems.  Then we could whine about 8 mpg instead and how that fuel dilutes oil.

Solid lifters.

Oh the joy of adjusting them regularly for peak performance.

Just spent $5k getting the lifters, camshaft, etc... replaced due to this AFM... only 125k on the truck, not a fan of this poor quality
