I have a 2008 Avalanche with a 5.3L V8 engine with Active Fuel Management. I was driving with the cruise on and noticed a clattering and banging under the truck until I accelerated just a touch and the clattering stopped. Turned out it was the AFM system. I bought the Range device. I plugged it in with no issues. I drive every day with the AFM disabled. The engine runs in V8 all the time with no noise. Replacing lifters is $3,000 and replacing the engine is $7,000. RANGE = $199. Nuff said.
