Will this AFM disabler work with my GMC Acadia or Chevy Traverse?

No, the RA003 AFM/DFM Disabler is specifically engineered for GM full-size trucks and SUVs (Silverado, Sierra, Tahoe, Yukon). It is not compatible with mid-size crossover SUVs including the GMC Acadia, Chevy Traverse, Buick Enclave, or Cadillac XT5. Using it on these vehicles will cause RPM fluctuations and performance issues.

How do I confirm if this device will fit my vehicle?

The best way to confirm compatibility is to send your 17-digit VIN number to service@egrperformance.com before ordering. Our team will verify your vehicle's engine and fuel management system within 24 hours.

No tools, wiring or programming required. Installation takes less than 2 minutes.

Prepare Your Vehicle: Turn off the engine and remove the key from the ignition. Wait 30 seconds for all vehicle systems to power down completely.
Locate the OBD-II Port: Find the 16-pin OBD-II diagnostic port under the driver-side dashboard, near the steering column.
Plug in the Disabler: Firmly insert the RA003 AFM/DFM Disabler into the OBD-II port until it clicks into place.
Verify Power: The device will illuminate a solid blue light when powered on. If no light appears, check your vehicle's OBD-II fuse (often shared with the cigarette lighter).
Start Driving: Start your engine and drive normally. The disabler activates automatically, permanently disabling AFM/DFM while plugged in.

Important Notes:

Unplug the device before dealership service to allow full OBD-II system access
Unplug during long-term storage (3+ days) to prevent minor battery drain
No firmware updates are required for supported vehicles

Excellent results

Easy order, prompt fulfillment and performance as advertised.

Unit doesn’t delete the auto stop. Vehicle seems a little more overfill but I’m not sure that it is true deleting the system as it is supposed to. But haven’t truly drove it enough to be sure

Amazing purchase

My 2009 Chevy Silverado hybrid,I had the entire motor rebuilt but always had problems with the hybrid. When I finally got my truck back it was completely running like shit and I was very upset a mechanic friend told me about the AFM that just plugs into my OBD sensor and he believes would resolve my issue, of course I was skeptical it couldn’t need this simple but once I plugged it in and my truck ran like a new truck I mean everything just completely went away all the skipping and pudding it was doing even the tranny slipping went away I don’t think that even makes sense but bottom line this device is amazing and I can’t thank you enough.

Thank you so much for this incredible, detailed review of our EGR Performance AFM disabler for your 2009 Chevy Silverado hybrid—we are absolutely thrilled to hear how this simple plug-and-play OBD device completely transformed your truck’s performance and fixed those persistent issues!

We completely understand how disheartening it was to have your entire engine fully rebuilt, only to still struggle with frustrating performance problems caused by the factory AFM system: the engine skipping, misfiring, hesitation, and even the unexpected transmission slipping that left your truck running poorly. It’s exactly why we designed our OBD2 AFM disabler specifically to address these common AFM-related pain points for Chevy Silverado models, including hybrid variants, with a no-fuss, tool-free installation that locks in full-time V8 power and eliminates the factory AFM system’s consistent reliability and performance drawbacks.

Stories like yours are exactly why we do what we do—we’re honored that our product was able to restore your 2009 Silverado hybrid to that like-new driving feel you deserve, even when you were skeptical that such a simple solution could resolve your long-standing issues. We can’t thank you enough for sharing your real-world experience with other Chevy truck owners navigating the same frustrating AFM issues with their vehicles.
If you ever have any questions about your AFM disabler down the line, or need any support for your Silverado, our team is always here to help. Thank you again for choosing EGR Performance!

Eliminates hesitation.

I have 183,290 miles on my 2014 GMC Sierra RCSB SLE. I have not had any issues with AFM. The only thing I have had to do is change my front upper A arms. No engine or tranny issues. I retired last year and don’t drive as much so I decided to deactivate running in V4. It fixed any hesitation that I had with the V4/V8 transition and is more enjoyable to drive. Glad I got it.
