Doing what it said it would. Only had it two weeks. Simple to use. Good to go so far, glad I found 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.
