Great device! I would recommend this to everyone. It gives you just about every piece of information you could want!

I wanted to get a little more towing power out of my Tahoe. I pull a 22 foot boat on the weekends, and needed some extra ummph. With a cold air intake, MAF, and Gibson cat back, I needed to remap the ECM. I choose the Cortex because of all the features. It really woke up the truck, and it's super easy to use. Just plug it in and follow the prompts. The only thing I don't like, is that the clock on the radio needs to be reset after installing the new map. But, I can live with that. Auot Anything has the best prices on the these devices. I highly recommend it.

I have a 2013 Tahoe with the afm/dod it was very annoying. I was able to select the 87 advanced tune and disable the 8 to 4 cylinder mode with this tuner it firmed up the shifts other than that i really haven't noticed any difference.
