On my way home last night, I took a road that had some pretty good hills so I could test a scenario to confirm the AFM was fully disabled with the Range installed. Approaching a long (1/4 of a mile or so ahead of me) upgrade of probably around 25-30 degrees from horizontal, I slowed down to 35mph and set the cruise control. The SS took the hill in stride with all 8 cylinders clicking. No lag. No downshift. No ugly exhaust sounds. It was great.
Also, as forty5th requested...

I unplugged the device when I got home and will drive without it long enough to make sure the AFM "performs" as intended. Stand by.
