I have been at odds what to do about the AFM system on my 2011 Avalanche. Then after reading the reviews on the Range device, tried it and love the smooth acceleration I get. Gas mileage dropped a little, because I'm having fun driving this thing. Too bad GM didn't put a bypass switch of the AFM system on these trucks or have it as an option. I HIGHLY recommend this device if you can't stand the constant shifting into V4 from V8 and losing out on the acceleration these vehicles do have.
