Worked immediately when plugged in. No more rumble and shake when engine drops into 4 cyl mode. No noticeable drop in gas mileage. Love it!!

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.

Hardest part of installation is running wires and stuff. Bought this tuner after reading reviews on others.Bully Tech support is very helpful! Installed performance tune and drove to work for a week. MPG went from 17 to 20! Installed tow tune and pulled my 5800 lb travel trailer with full water tank.Tow MPG went from 9 to 13 and went faster up the hills with less downshifting! The driving coach takes a few drives to get used to but not a biggie!
