When they removed my motor from the silverado they broke the AFM connector in the back. Rather than repair the connector I just deleted the AFM. LS1tech also convinced me. They say that it creates a horrible sound when 4 cyl mode kicks in with anything but factory exhaust. There are also reports of oil usage (up to 1 quart a month) with it on. All that together just made me decide it wasn't worth the small mileage gains.
