I am in a similar situation. I bought D&D fatcat and air cleaner. Now I am trying to decide which tuner to run . I haven't heard of any real good tuners close by and the Harley shops I just don't feel comfortable with. Seems like every time I am in there it's different guys in the shop so I can't imagine very good techs to be doing my tuning. With that I am leaning toward an auto tuner either powervision or thundermax to get me going til next winter when I get with scott at Hillsidecycle for cams and some headwork. Good luck and I'll continue to follow your thread.

 

I have heard several good reviews on the Power Vision. In fact Devin and Kevin (DK) have the Power Visions on their bikes and are very happy with the results they receive. And of course you can't go wrong with the unlimited technical support by Fuel Moto.

Also, below is a Overview of EFI options, this may also help you out

both, you need a tuner that can be programed to be dyno tuned
