Question for anyone that can help me. I am very confused on what I need to do on programming my bike. I can not get a straight answer from my local hd. I have an 07 nighttrain that I am adding the screamin eagle heavy breather and the Vance & Hines shortshots staggered exhaust. I need to add a programmer, do I do a screamin eagle pro tuner, a Dynojet power commander III, or Dobeck performance TFI? I know that I will have to Dyno my bike too, but I am confused about which programmer to use and which one is the best way to go. Any help is greatly appreciated.
