Is anybody with a flash tuner seeing an actual MPG increase. Basically wondering if it is worth it to have. I don't plan on towing any heavy loads and my days of high performance are over. I really just would like to make my 3rd gen expy as "pocket friendly" lol as possible. My buddy's hemi ram picked up a few mpg with just a drop in k&n panel filter. I wonder the the expy will do the same. Any suggestions fellas?
