This means we no longer have to deal with the slight “rumble” that can occur when the AFM activates. Not only does this make for a smoother ride, but it also enhances our vehicle’s overall efficiency, especially during those lengthy commutes or road trips.
One of the most notable features is the simplicity of installation. We just need to plug it into the OBD-II port, and voilà, we’re good to go. this straightforward process eliminates any need for tools or a trip to the mechanic. For us, that ease of use was a significant bonus! since making this switch, we’ve noticed our trucks-like our 2012 Yukon and 2007 Avalanche-maintaining V8 mode effortlessly. This has resulted in a noticeably improved driving experience, with less wear and tear on the engine as we no longer have to worry about the system shutting down cylinders.
Our extended experience has shown that the unit holds up well even during long drives. For instance, on a recent 300-mile trip, we achieved a consistent 17.5 MPG using the AFM setup. Though, with the disabler in place for our return trip, we enjoyed the same mileage without the annoying fluctuations of the AFM intermittently engaging. Excitingly, we felt like we were powering through the drive without the vehicle’s efficiency being compromised. It’s engaging to experience that difference firsthand, especially for those of us who appreciate the power of a full V8 engine.
