What is a "Fuelpak"?

I've noticed it mentioned here a couple of times. What is a fuelpak?

Fuelpak is a fuel management system from Vance & Hines.

Is this something different or in addition to something like a SE super tuner? Do you need both or will the tuner do it all?

It is the same idea. They are intended for the same function. Both change the fuel mixture to allow the bike to run richer than they do stock. They are too set up too lean stock.

Although, the super tuner is a device that allows you to re-program the actual ECM. It doesn't stay attached to the bike. A Fuel-Pak (and a Power Commander as well) stays plugged between the ECM and the ECM wiring harness. The Super Tuner changes the ECM output commands altogether while a PC or Fuel-Pak simply "reinterprets" the stock output commands.

Assuming they are setup and functioning correctly, the end result is the same. There are benefits to each, I suppose.

If you intend on building cylinder pressure,(ie cams, or reducing combution chamer volume) those DO NOT have provision to manipulate the timing requirements.

So if you are upgrading exhaust and intake on a bike, is it required to also retune? Im looking into the V&H 2 into 2 big radius and some sort of intake for my Iron. Would the V&H fuelpak work fine for me? or are there better options at tuning for new exhaust/intakes?

From what i've read here on the forum, teh V&H fuelpak will work for what you are wanting to do, but it seems that several of the guys on here think that there is better options. I think most will ask you what other mods do you think you might want to do. If you plan on making other mods (ie, cams, pistons, compression, etc.) then I think they are more in favor of the thundermax, power commander, etc.

Im more just looking for the bolt ons. Exhaust and intake are probably the only things I will want to do with it. at least for the time being.

Right now I am looking at the following upgrades to my Iron.

-Harley Forward controls (needed for the V&H Big radius 2into2)
-V&H Big Radius 2into2 Exhaust
-Some type of intake (cant find one that I like)
-Fuel management like the Fuelpak.
