Works perfectly. Plugged it in, cranked her up, no more V4. Perfect!

I was a bit nervous after reading the instructions and warnings about making sure that all devices that use power from the car battery are turned off and/or fuses for them are pulled so I called the Hypertech tech support guys to make sure I wouldn't screw up. The instructions were very clear and the programmer worked perfectly. I was able to turn off the AFM system so my Tahoe no longer goes into V4 mode. I get better gas mileage & more horse power.

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 :)
