None of us know what you read or what you know. If your talking about your truck being demandated its helpful to state who did the programming so there's no confusion and we don't assume things.

Chuffing is usually caused by a plugged egr circuit. Yours is demandated, are you sure it's "Chuffing " or is it something else maybe ?

Yes it is chuffing out of the air cleaners. If you have the jakes on and let off its perfectly normal until about 1300 rpms. Then starts chuffing out the air cleaners. 2nd and 3rd stage.
