That’s kinda what Range Technology was telling me. There telling me they have sold the 2019 version for the 2020 models without any negative feedback. Just looking for someone that has tried it.

Had a range on my ‘13 no problems ....im sure its same on the 15+ models. A 2020 model is simply a 19 .... GM waited to release new models and 20 is just a carry over year.... like 13-14 modrls.

Good to know. This is my first 5.3 with the AFM. I’m guessing GM has worked out all the problems with it.

I just got a 2016 and it was the first time driving with the Chevy AFM. It’s definitely noticeable and annoying. I got a used Range from a friend and it does the trick. I’d say go for it.

When I bought my Range AFM disabler there was talk about when GM would start putting DFM into which vehicles. I guess some trucks will get it in 2019/2020 but I'm unclear when the Tahoe/Yukon/Denali will switch from AFM to DFM. Range says they do not support DFM as of yet.
