I just shot them an e-mail too and received a response within 5 minutes, so I guess I will be beta testing one of these also!  I guess they were desperate for a 6.2L/10-speed combo!

 

 

Curious to see if this will help with the rumble on decel we're experiencing. Doubtful but you never know!

He is shipping one out to me today!  I'll let you know soon.  That is the #1 thing I am curious about myself and is the sole reason I agreed to test.

Awesome, keep us posted! Appreciate you being the guinea pig haha

 

Also curious to see if like with the AFM disable it, as a byproduct, disables start/stop as well which would be sweet.

It DOES disable auto start/stop.

 

His email to me specifically answered that question.  The device will disable the DFM AND disable the auto stop/start.  There is no selecting between the two....it is all or nothing when plugged into OBD2.

Heck yeah, that's great news! Look forward to hearing how it works out.

Got mine today. Unfortunately my truck is at the dealer getting a vibration diagnosed. Hoping to get it back by the weekend. 

 

Compared to AFM I agree it is not very noticeable. I am most interested in it because i plan to get the new carven catback soon and don't want the noise. Also happy that it disables the auto off feature.

UPS will deliver mine tomorrow while I’m at work. So I will take a spin once I get home. Fingers crossed that it will work well.

Weird.

 

I emailed Range and they responded within 5 minutes stating the below:

 

If your vehicle is equipped with DFM we unfortunately do not have anything available for your particular application at this point in time. We are actively looking into developing products for vehicles equipped with DFM, but we do not have anything currently available or in beta testing for them. Thanks.

Mine should be here for beta testing this weekend.  Trust me, if you drive a 6.2 with Corsa exhaust and CAN'T tell when the DFM kicks in you would have to be deaf or not paying any attention whatsoever.  Its incredibly obvious.  Before the exhaust, I could tell mainly cuz I'm OCD about that stuff, but it wasn't all that obvious to someone who either wasn't listening for it or paying close attention.  Even before the Corsa exhaust broke in good it wasn't that terrible, and to be honest I wasn't real thrilled with the exhaust cuz it wasn't all that much louder or meaner than stock.  But after a few months that exhaust got good and broke in and significantly louder and sounds amazing.  You just hear and feel the stupid DFM.  I have a problem more so with the principle of being forced to use DFM if you want to own the best looking truck on the road.  Let it be an option, which you push a button to turn ON, not off.  Kinda how the auto stop start SHOULD be.  If I want to save gas (which is probably debatable anyway) then great, let me push a button to do so.  But if I didn't buy a damn 6.2 truck for gas mileage (hello 99% of us out there) then let me run all 8 all the time if I want.  Just another way our government wants to control our lives.

 

Damn, I fell off my soapbox!  Guess I'll stop now.

We all know they are not selling them lol. But it sounds like to me that they have sent out all the beta testing units?

You sound like me!!! We are OCD twins!! LOL.. I have the 2020 TB 5.3 10 speed and I can definitely feel it, sometimes the truck even stumbles getting on the gas from a slow turn... I was complaining about the exact same thing to my wife last night about the Auto stop and DFM... I bought a TRUCK not a Prius.. I want my 8 cylinders 100% of the time and don’t need my truck shutting off at every light or stop sign... I can’t see how it really helps Fuel mileage anyway... I’m averaging 15.1 MPG with over 5300 miles on my truck since I pulled off the lot, this is with DFM working... I look forward to tracking mileage after I can delete the DFM... Lets not even talk towing mileage.... 9.9 towing a 8x 12 90% highway... LOL... Rant over... I look forward to hearing how these test units work out..

They told me that they had all the testers accounted for... Guess we lost out, Now we wait and prey for great feedback on the units

L9 is your friend til u get a range brother.  L9 prevents DFM and cuts out the auto stop/start.  Yeah u lose use of 10th gear, but it's not that big of a difference.  With a 6.2 I'm averaging over 18mpg.  No towing anything heavy yet tho.  I lost my butt cuz i originally bought a 5.3 and the DFM with that 8 speed it had would feel like a cell phone on vibrate in the center console.  Drove me nuts, so i traded it 1 month later for a 6.2 and lost about $4K on the trade plus had to buy a truck that was $10K more expensive.  I love it though and wouldn't trade it for anything else.  Favorite truck I've ever had out of 12.

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
