I have owned my 2012 Chevy Tahoe for approximately two years. During that time, I have almost been involved in a few accidents because of the throttle delay. My research showed that it was the AFM system that was causing it. The Hypertech programmer removed the AFM programming and my acceleration was immediately improved. O-60 time decreased from 11.5 to 8.99. Gas mileage increased slightly (3-5 mpg). I was preparing to sell the Tahoe, but now I am going to keep it.
