Exhaust / Disabling AFM

[rwi2112]

I talked to my exhaust guy about putting duels on 2015 Silverado. He told me if I had the "Active Fuel Management" system that it would sound like a wet turd when it kicked in to 4 cylinder mode.

I have found that the Hypertech Max Energy programmer will let me disable the "AFM" mode. Have any of you guys used a program to disable your "AFM" ? I went on You Tube and listened to some exhausts but they all sounded to me like they were hitting on all 8 cylinders. I have the Max Energy on my 2010 Camaro and I am very happy with their products, just wondering about on a 2015 Silverado.

 

Thanks, Wayne

I used on my 14 GMC. I shut of the V4 put the TM at 50 percent. I left the engine tune alone, I was running E85 locally and reg gas on trips. Made a big differents.

Made a big difference on trips? Your gas mileage was a lot worse or how did it make a difference? I pull a 5 X 10 enclosed motorcycle trailer some times but that little thing is like not pulling anything.
