Recently picked up a 2020 RST 6.2 / 10 Speed...coming from a 2007 4.8L Silverado (that is still going). From researching I didn't like anything about the AFM/DFM and looked into the Range DFM Disabler. Ordered one directly from Range and "tried" to confirm with tech support that it would work on the 10 speed. One tech hung up on me and the other told me it wouldn't work on the ten speed and pretty much hung up me after. My last ditch effort was to complain on their Instagram page and I received a response within 20 minutes. The rep wrote me and said he confirmed with tech support that they have a small percentage of units where 10 speed owners had issues but, for most it worked fine. That was good enough for me and I plugged it in. Have around 600 miles on it and there is no issues. When it's not plugged in (installed AMP steps and need a splitter now) I can feel there is hesitation when launching and when stopping as well. When it's plugged in it goes away and runs fine. Unless there is an issue down the road I'll leave it plugged in forever. Not easy to find current information about this, would recommend members order directly from Range. With Amazon your not really sure how old these things are.
