A person I know that lives in a small town (about 1200 people) about 100 miles from Jamestown and our HD dealer put a turbo on his 2009 trike back in 2010. He was dissatisfied with the power of the TG and wanted more power and thought it would be really cool. At a cost of thousands he added the turbo plus just about all the accessories you would need to make it into a Screaming Eagle. Anyway after doing this his mileage dropped to around 15 to 17 on the highway. He had a tuner added and other things and finally took it back off last summer. He could barely make it from his hometown to Jamestown on a tank of gas. With the turbo off he did the sprocket update and a couple other things and now it has power and much better gas mileage. Also he had to replace the right lower as that is partially cut away to make room for the turbo.
