The biggest benefit so far is better shifts, they feel quicker and more sure now. The gas mileage is up less than 1/2 mpg for city/highway and a little more for highway driving. The Hypertech will take 4 years just to pay for itself at that rate. That said, I am eager to find out if the Hypertech helps when I put oversize tires on. On my old truck bigger tires cost 3 mpg. I hope to at least break even with bigger tires and the Hypertech on the newer truck.

Couldn't find a video for an 08 Tahoe that showed where this chip was supposed to be installed but after unplugging a couple connectors and comparing the pins, I found it. At first, I didn't realize any difference but then I hooked up my fishin boat and instantly noticed the performance. This chip will NOT improve your 0 to 60 time but it WILL improve towing! The other thing that I did notice was a small change in shift points; MUCH smoother and I can tell my driveline appreciates it! Get one :)
