Fuel Programmer
What are the options for fuel programmers when you get an intake and full exhaust on an FI Harley. First off, is it just a way for the dealership to make money? I thought the fuel injection system would be able to compensate for the extra air? Secondly, not sure the brand the dealer carries. I'm pretty confident there are better units out there for the money. Is it a necessity? If so, what is the way to go? Thanks for all your help.

Yes you do need it if your doing AC and pipes, I went with the PCV from Fuelmoto, great product and service.
They will pre program it for you based on your setup and it's just plug & play and if you change anything in the future they can send you a new map or you can change things yourself with a laptop.

Mastertune TTS is the most versatile, Nightrider X14iED is the least expensive (~$100), Power Commander Five (aka PCV, PC V) is a very popular and excellent compromise. It really depends on what you're going to do from here with your bike. If you are going to quit with the AC and exhaust, and aren't going to race, then the Nightrider is all you'll ever need. If you're going to quit with the AC and exhaust but will race (or want better dyno sheets), then the PC V will set you up quickly and fairly inexpensively. If you're going to eventually add cams or other internal components, the the TTS is the only way to go.

V&H FuelPak is also another option and is what I have. Very easy to program. But if I would have known about the X14IED's beforehand I probably would have went with those as they do the job just as good and are much cheaper

I ordered the exhaust through the dealer (yes, I know there are better alternatives but had a gift cert to burn) and they started to get into some kind of $450 programmer and $250 of tuning and dyno time. I was like get me the **** out of here.

Anasthesia, my bike came new off the showroom floor with high flow air and a ThunderHeader, full factory warranty. The stock ECM can quite handle this modificaton. I live 7 feet above sea-level, in Palm Harbor, Florida, the bike has been up and over the Continental Divide on Trail Ridge Road out of Estes Park, Colorado, (family has lived there forever). Never missed a beat, but gas-mileage went way Tdown, 35-6-7. Performance, however, did not decrease. Ran like it always does. TechDiver500ft has a good point, further modifications will require a change, usually the electronics come with the kit so it's no worry anyway.

I have the PC III with a dyno tune on my XL50 and so far so good. If running the pipes and AC you will need to richen up the mixture for sure. I'm thinking about running the X14IED on my 1200 C just to get it a bit better since I'm not 100% sure if there is any tuning on that bike and it has slip on's and SE AC and that is as far as i'm going with that bike. IMO you cannot get the PC III or PC V right without a dyno tune so if that is something you don't want to get into then try out the X14IED and be done with it.

Nightrider also has the ViED, which I have, that is adjustable so you can 'tune' your A/F ratio. Good quality piece, way cheaper than dyno or a tuner.
I won't be using anything else until the 1200cc kit.
