Looking for those who have done a full DFM delete, IE: New cam and lifters.
where did you get you ECM reprogramed? how much did it cost?
 
According to Donslife on YouTube, he states that putting transition in manual mode, one less than maximum speed, ie: L9 for 10 speed, L7 for 8 speed, M5 for 6 speed - will disable DFM/AFM. He owns/drives a Silverado and says that a viewer has validated his claim with an ecm reader. If true, this is an easy no cost way to disable AFM/DFM. This is just FWIW, so please don’t shoot and gut the messenger.

Yes, this does work...but the question here is not how to temporarily turn off DFM, as that doesn't solve anything. What the OP and many others are looking for is a path to actually cure the DFM issue - i.e. remove the offending lifters. To do that we need a way to permanently remove all DFM functionality from the ECM, and as of yet no one on this site has confirmed that that can actually be done.

OP - I have yet to find any confirmation that this has successfully been done anywhere (DFM specifically, I know AFM deletes have been done), and knowing how difficult any kind of programming is on the T1 and newer trucks, i'm not confident that it's actually possible. But if it is, i'd love to know too.
