Yes, but 15% or from 50 to 57.5MPG. Is chip tuning the first thing you would recommend? You and I both know how hard it is to get to that, and if there was an easy add-on purchase that "measurably" bumps up your MPG by 7.5 I would buy it, who wouldn't? Buy and extra 100miles per tank fill, I want that gadget. He still claims he averages 58MPG with all the "performance" mods he made. Just continue to keep and eye on this thread it gets funnier.
