Hey fellas,
I’m trying to look this up everywhere but still can’t get a definite answer. My 2025 AT4x 1500 6.2L, based on the window sticker it is equipped with DYNAMIC Fuel Management, is there any way to disable this?

I owned a 2018 Sierra 1500, and was easily able to disable that through a tuner. But with these new trucks I don’t see the V8 and V4 logo when pulling it up on the fuel economy page on the dash. And from my understanding this will overtime cause problems but I’m not here for that and trying to take any prevention mods possible.

If anyone has any information on this, it would be greatly appreciated.

Looks like it passed beta testing...
