I have a 2025 Sierra 1500 SLT 5.3L. I know the history of the AFM, DFM problems. I figured I would buy extended warranty or trade in around 50,000 miles. Then I see all these disablers and figured I’d try one. I only have 11,000 miles on it. Not many work on a 2025. I found one that said it does, Fullforce. I installed it but not sure if it’s doing anything. Contacted the company and of course they said it’s working. They are not very helpful and went I questioned why there is no name on it they said someone would get back to me and never it. They said I could return it. My question is does anyone know how I can tell if it’s working. I have a Thinkcar scanner but can’t find anything showing me it’s working. Also if I return it what is the best one that works on a 2025? Thanks for your time.

First off, welcome.  Second off, wrong forum section.  This is for the upcoming 2027 new trucks.  Your post should have been in the 2016-2026 section.  

 

Third, I can't speak for the cheapo strange brand name ones like this "Fullforce", but the reputable ones do work like the Range devices.  The Range DFM module for 2022.5-2026 trucks for sure works with those year ranges because there are changes to the ECM on the 2022.5-2026 trucks in where many of the OBD based disablers won't work.  The Range RA007 plugs directly at the ECM and NOT the OBD port.  

 

This is the Range one you really want - Range Technology RA007 DFM Module

 

Range's OBD one does not work on 2022.5-2026, so I would highly question this cheap $85 "Fullforce" one.

      first oil change - 2026 2500HD gas

      Yeah I don’t leave ANYTHING just sitting supposedly maintaining my battery on a vehicle or RV for multiday periods. I connect a charger as needed to provide a full charge, then disconnect it and either monitor the battery or follow a set schedule for periodic charging.

      NEW TRUCK

      Get the 5.3. I`m not a Ford guy.😉   I think these L84`s are less problematic than the L83`s. Certainly less than the L87.

      NEW TRUCK

      By PUSSLEGUT · Posted

      I have finally paid off my mortgage and can now purchase a new truck. I would greatly appreciate any opinions on the purchase of a new 2026 GMC Denali 5.3L or 6.2L with the Denali reserve package. I am not interested in the 3.0L.  Or should I go buy a Ford?   Thank, John

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.
