Just installed the new fuelpak 3 on my 13 fxdf yesterday. The map install went very smooth. Took about ten minutes from start to finish. The canned maps are very limited to mainly v&H pipes. I have Se Sp slip ons so I had to find the close match,which was the V&H 3" slip ons. My A/C is a stage 1 big sucker. Took her out yesterday and noticed right a way that all the decel pop was gone. The motor pulls much stronger all the way through the RPM range. I also noticed that the oscillating feeling at steady cruise speeds of 35 to 45 mph was almost completely gone. The bike has a much better over all feel to it now. I got to say I am very impressed with this new tuner. I haven't tried the auto tuner feature yet but honestly it is running great with just the canned map. When I have a chance to do a auto tune run I will post back how it went. So far I could be happier with this unit for the price. It is a flash tuner so no need to leave it hooked up to the bike, you can pull and clear codes or leave it hooked up for live sesore data on your iPhone.
