One other option to the FP and DFO/TFI is the TTS Mastertune. I like it more all the time. The ability to tune your own bike instead of depending on a dyno/tuner is worth the $400+ price it costs.
Being able to adjust the speedo, save the original calibration, turn on/off EITMS, and a bunch of other cool stuff really comes in handy when it's time to do it.
The fact that it doesn't leave any hardware on the bike is a major plus as well.
I've got an old SE Race Fueler my 07 came with when I bought it used. This little device works pretty good too and adjusts with a few electrical "pots" by simply turning the screws to dial it in. It adjusts pretty much like a carb does.
These devices, when they work right, are pretty decent and get the job done but they are extremely limited.
My advice: If you plan on keeping the 07 or newer EFI bike for a good long time then the TTS is more than worth it.
Why would anyone want to dumb down a smart device like the EFI system with O2 sensors?
That's essentially what a Fuel Pak does.
At the very least; get a PCV.

your not gonna break anything but you probably will experience some popping especially on decels and will also be running hotter. I personally like the fuel pak but then again I have no plans on doing anything else to my ultra that its on.

I should have worded my earlier post better.

I bought a 2005 Heritage with V&H exhaust, fuel pak, and stage 1 a/c. Every so often it would miss? Contacted V&H and they were able to help me make necessary adjustments and bike runs great and gets better fuel mileage. Very easy to change mode settings.
