Did not adjust as many items as I thought it might. Easy to install. Just wish it did more for my truck.

I got 8x,xxx mile on my 2011 Chevy Silverado with the 5.3 and it started to smoke blue smoke for a few seconds after I start it. So I bought Range device. It works and my truck don't smoke anymore when I first start it up. My fuel mpg is about the same.
