I have a range RA003 from my old 2019 Tahoe 6.2 but do not want to try it on my new 2023 6.2 z71 Tahoe. If someone does, let me know and I’ll lend it to them.There’s a guy on the 21-up Tahoe Facebook page that claims the previous gen Range has disabled the DFM on his ‘23 Tahoe. I pressed for more info and confirmation and he went silent. I’m not buying one to experiment, and would have to imagine Range tried it or knows it won’t work, but if anyone has an RA003 laying around and wants to give it a try, please do!
