Based on 15 minutes of use, it did what it is claimed to do, delete the AFM on my 2014 Suburban 5.3. Watching the Economy setting on the vehicle's Info system, the 4 cylinder operation indicator no longer appears. Most seat of the pants indicator is when coasting, the Economy is shown as 50 mpg, not 99 mpg.

I can't predict what the results will be. I do know that when I started the truck and drove down the road it was a definite difference in sound and power. I hope I didn't wait too long. I have 60,000 miles on the truck. I got this hoping to prevent lifter problems later on. Only time will tell.
