disabling AFM on Yukon?

I'm looking to see if anyone here has deactivated the AFM feature on their trucks. Active Fuel Management. 8 to 4 cylinder operation.
I have read some GM service bulletins regarding this feature and related oil consumption.
I just found this device online and wonder if anyone has used it or something similar with success with no ill effects.
