We installed stock non-AFM cam and lifters in our 2008 Chevy Tahoe work truck. Not a hot rod.
Just trying to delete DOD/AFM with the Diablo InTune i3.
Getting through the menus to AFM Delete, select "Off" and nothing happens. No "Continue" or other verification. If I go back, it just repeats the same.
Am I missing something?

Re: 2008 GM 5.3 AFM Delete?
you need to select the preset ECM tune you want to install...
then choose to Modify it...
go to the AFM/DOD setting and disable it/turn it off...
Then exit back out from the Modify Tune menu..
Then you need to install/apply the tune...
and that will reinstall the preset ECM tune with the AFM/DOD setting disabled...
