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.

The Jet Module did give a little extra power thru th eRPM curve, but most of all it did change the shifting points in the tranny so that now it doesnt shift in and out of overdrive when traveling thru the mountains. I had some questions prior to the instalation and called customer service and they were verry helpfull with all my questions.

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.
