Disable AFM in Colorado?

Not really possible since Programmers marry themselves to a single vehicle..

so if someone had a programmer and was using it on their truck they could not do your truck.

So if you want to turn off AFM you need to buy your own device.

AFM = Active Fuel Management (2007-2013 AVYs) which is where the engine goes from 8 cyl down to 4 cyl when driving steady speed... it has been linked to engine lifter issues and oil usage see problems engine section
 
Look into these a little, if I ever get a second gen I think this is the route I will go

Thank you for recommending the Range Device. After a little research I'm going to go with the Diablosport Intune i2 instead from Diablew Tune.
