Actual Range Tech Customer Reviews:

  • I didn't even realize just how rough my 2011 silverado was running, that is until I plugged one of these bad boys in! It instantly ran smooth from the first start. I'm really eager to see if it takes care of the burnt up spark plug issue. I'm hopeful it help control the oil consumption issue as well. One tank in and the milage is about normal usually 18mpg to work and 21mpg on the interstate.
  • I have a 2014 Silverado Z-71 and I just installed it and wow! I can definitely feel the difference love this, it’s definitely got more power and the transmission shifts smoother now I highly recommend this.
  • This turned my 2017 Silverado into what felt like a sluggish four cylinder car half the time to full power and even noticed smoother shifting of the trans great product

An active fuel management (AFM) disabler is a device that is used to disable the active fuel management system on certain vehicles. The active fuel management system, also known as cylinder deactivation, is a technology that allows an engine to switch between using all of its cylinders and using only some of its cylinders, depending on the driving conditions. This can help to improve fuel efficiency and reduce emissions. An AFM disabler is a device that is installed in a vehicle to prevent the active fuel management system from functioning, allowing the engine to run in full cylinder mode all the time. Some people use AFM disablers to improve performance or to prevent problems with the AFM system. However, disabling the AFM system can also reduce fuel efficiency and may void the vehicle's warranty.
