It definitely works and in my Suburban it does not stay on when the ignition is turned off.

2007 Jeep Wk Lifted

Reviewed By Eddie C (NEWPORT, NC) Reviewed for a 2007 Jeep Grand Cherokee —3/20/2015 8:16 PM

Does the job as advertised. Recently lifted my jeep and put 31" tires on. Prior to installing the calibrator, the speedometer was off 7 mph. When reading 55 on speedometer, GPS showed me going 62. After calibrator installed, speedometer is dead on with GPS speed tracking. Would definitely recommend and may upgrade to the max energy software.

I could not feel a difference after installing the Range AFM Disable Device, even for several days other than it drained my Tahoe battery when leaved mu Chevy parked for a couple of days ( it does advertise that would happen anyways ) I drove my Tahoe offroad, on the highway and in mountain roads and couldn't feel the difference, I guess it didn't worked.
