How does the RA007 DFM Module compare to the RA003B AFM/DFM Module?
For a 2024 Z71 Tahoe

RA007 is the only one that will work on the 21-up gm suv’s

It looks like the RA003B is for the Camaro, not our trucks.

Anyone used the DFM/Auto start all in one disabler?

Overall very pleased. I am waiting to see what actually happens to mileage.

It won’t affect your MPG as mush as you think…

To be honest you might notice 1-2 less mpg. Which IMO (and based on your experience so far) does not out weigh the increased drivability, improved driving experience, and potential increase of reliability.

It sounds interesting…there’s a little bit of an install process removing an ECU connector and fender liner. I was hoping more for a dish connector easy install.

Curious how it works out for you. Thanks for the info on it.

I installed it appx 5 weeks ago, super simple. What I noticed, first drive it seemed as though the trans wasn't hunting meaning wasn't shifting as much and maybe what I felt prior was cylinder deactivating, not sure but really smoothed things out. Pulled the boat the next day and thought the same thing. Really impressed and enjoy start/stop not active. Like the AFM disabler I put in my '15 I think it may have picked up MPG.

Did you remove your wheel and whatnot like the instructions recommend? Or could you gain access without doing all of that?

Also, do you folks believe that you'd need to remove the module prior to taking the truck to the dealership for miscellaneous service?

Park with the wheel hard over to the left. Use a floor jack to raise the frame a few inches and slide on your back from the nose. Simply bend the fender liner out of the way and unclip the wiring harness and snap in the new module and plug the original harness on to the new module. Pay attention to the install video how they both clip and unclip.

Could you also raise the suspension to the highest setting and avoid having to use a jack?

Miscellaneous service? It should depend on the service.
Either that, or whether or not the dealer / mechanic is a nosy busybody.
