Anyone out there have/use/recommend one of these and see MPG increase of their claim up to 34%. Can someone explain to me the concept, please do not copy the add I can read that myself.

at 170.00 it would pay for itself in a few months.

just curious!

 

I dont have one, but I read the article in JP magazine where they tested it on a TJ and got 1-2 MPG

Here's some other threads about it

ok,

so i have read all the other threads andbasicly one guy in the whole forum used it and saw an increase, not enough for me to go on. in contrast my Hypertech a lot of people use it on here and report up to 3 MPG. I will wait till i see at least ten people report their MPG increase by 2-3MPG before i consider it. Thanks

 

You can improve your own MPG 1-2 mpg and maybe better just by changing your driving habits. That won't cost you a thing.
