So far so good

My GMC Sierra 1500 4x4 has 180k miles and has been making a rough roaring noise when going down the interstate while in 6th gear over drive. Rpm gauge jumps when the noise starts / stops. Combined gas mileage is about 16 mpg. After Installing the EGR AFM device the engine stays in V8 mode all the time and the engine does not make the rough roaring noise at any speed. Gas mileage has increased to around 17 to 17.5 average mpg per tank. I am very pleased.

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.

Works great. No more horrible shifting sounds. Runs very smooth now.

truck runs great you guys are on the ball saved my motor

AFM Disabler for GM V6 & V8 Engines (2005-2020) 5.3 Chevy Silverado

It works great . Also check engine light went out . Very cool

Update, I own a 92 Bronco 5.8 with 3" Lift, 35's 4:10 gears with EOD transmission
Average 10MPG. Just set up new Headers with Block off kit. Now averaging 11.8MPG, no lean issues at cruising speed with full throttle response. If you are going to ERG Headers, I suggest two items, Proform self-locking header bolts #66756 and Fel- pro Header gaskets. Far superior. Expect check Engine light 332 indicates EGR Off.
