All I am saying is it works. Saves fuel and no harm done. Results like I say will vary. A person can go out and spend god knows how much on a device which may show a more accurate figure. Like I say fact is saves money. Secondly remember as we all know fuel economy varies so of course I have all sorts of results. Me I am fine with this. With the pandemic we have going on not going to buy a tech2 just yet with the world economy in tatters. Perhaps after the pandemic I will get a tech 2.
