DFM disabler released

[nick14226]

@nick14226, thanks for that explanation. Makes total sense. As I recall, the Z71 available w/ the 5.3 or 6.2 in 2022 as well, correct? Guessing the 6.2 has a bit more gusto w/ cylinders deactivated than the 5.3, so that could also be a difference; you haven't said which engine you have. For sure exhaust mods would make the changes more noticable....bummer it is so obnoxious for you. Glad you have a solution you can live with though.

Sorry, yes 2022 z71 5.3
The corsa had no impact on the drivability. It’s well designed and eliminates the flapper, but no drone from DFM. Just can hear the cylinders kick back during decel at 14 mph, which again doesn’t bother me. I’ve 6.2 owners with the same complaints as the TSB defines that I experienced, so again, think you’re lucky
