i installed a cold air intake and a cat back exhaust and increased my MPG by 4. i installed the tuner, the truck has better performance, but killed the MPG gains.

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.
