I have a 2007 Victory Vegas. I have fitted different deflectors on the outlet and inlet Lloydz torque tube. I had a hard time finding anything close by to get my hands on a dynoed bike. This device was exactly what I needed. I had about 3 maps to choose from that were available from the Dynojet. None of these three had an AFR table to choose from. I had to manually adjust the AFR chart, which requires an understanding of the fuel/air ratio. But the device works very well. It's not a plug-in, especially if you get a card that doesn't already have an AFR table set up like I did. I'm sure there are many maps for Harley Davidson that have AFR charts, so that's probably a different story.
