It appears the second tune Han0 sent you has the decel popping restored. Not sure why you'd want that, but to each his own
..
Anyhow, these bike aren't really know for get MPG (KPL). I would get about 30-33 MPG in city driving, close to 40 on easy highway driving. After loading the same tune, I get around 25MPG city and low to mid 30's highway. This tune runs rich. I have gotten off the bike after some stop and go traffic and my pants smelled like gas. That said, I absolutely love this tune!
