GM Engine Issues

After costly maintenance to replace a faulty/compressed lifter spring, decided to disable AFM on my 2008 Silverado (6.0) truck. The Range device does that simply and efficiently. Quick to install and may be removed at any time. I plan to use it for the length of time that I own the truck. No more V-4 operation for me with its inherent risk of failed lifter springs on cylinders 1,7,4&6!!!
