2023 5.3 w/10spd DFM Disable

RangerDLA · Feb 27, 2023

Just traded in our 2020 Z71 for a 23TB. My first mood would be a DFM disabler., but the Pulsar LT and Range DFM disabler do not work on the 23. Anyone know of any other brands that make one for this year and engine/transmission combo? I hate DFM.

Wondering the same thing. I can't find any disablers that support 2023 models.

I wonder if you guys could take the refresh trucks to a tuner that has hptuners software and have that turned off.

There is nothing for the 22+ Refresh trucks. GM changed the electrical architecture in them and no one has cracked it yet. HPTuners doesn't have anything either. Their hack for the older trucks is to modify the ECU with an older chip without the encryption GM had in them so they are able to tune them.

I also was looking for one and ran across this. https://www.autostopeliminator.com/collections/gm/products/2019-silverado-autostop-eliminator
Am thinking about purchasing it but looks like it needs to pull the display dash to get to the wiring behind it... I'm not ready for that yet.

saw a video by these guys on what it does.

That controls the stop/ start function not the DFM.

I called Range and they said they will be coming out with a DFM disabler for the 2023 and newer models later this year. Anytime between October and December.
