Throttle body Spacers for 2011 Duramax

I have been trying to see if adding a throttle body spacer will actually add a bit hp and add the 2-4mpg which they say they do, anyone with knowlege know the truth?
I do a ton of driving and would like to gain a few more mpg if possible, but I'd hate to waste my money on something which is a total farse, & since a ton of people on the site are very mechanically inclinded, something which I am not, many of you should know, hopefully anyway.
any and all help in this regard would be a great help, thank you.

PS, I am also kind of interested in the Air Dog system, and if you happen to know about the advantages to this, i'd also appreciate your help in this matter, although I am now going to do some searching in here about this system.
My main question is about the throttle body spacer as I couldn't find anything on here thus far, but I am going to continue looking at both of the above.
Again, thank you

You should get every part advertised to save fuel. Before you know it, you'll be taking fuel out of the tank to make room for more saved fuel.

Don't forget the magnet on the gas doors to suck out the negative electrons in your fuel

When you do the throttle body spacer do you have to upgrade from a 1/2" kabibble to a 3/4"?

The LMLs have a "throttle body". Pretty sure it is for controlling vacuum in the intake for emissions/EGR.
