Well it took me 5 min to install this. I like how you can adjust what you want to see on the display. Not sure how much it saves in gas because I've not had it long. But you can tell it does something to the engine. The engine responds better when you hit the gas. My tahoe had a lag when you hit the gas. But now its gone. This maybe due to the cold air intake and flow masters I put on at the same time(All from auto anyting). All I know is it went from mild to wild in one weekend.
