Using Scanguage to tshoot codes and to help better monitor driving style and engine situation has saved me enough on fuel to buy the second one.

Installed the programmer on my 2004 Jeep Liberty limited. After installation i drove the Jeep on my normal commute and right away the MPG display started going up.It usually averaged 18 mpg,After a week it was averaging 21 mpg. Also besides the MPG increase it seems more powerfull under WOT acceleration.
