fuel pak?
This spring I'm planning on buying my first HD. (wide glide)
Im goin to put on an s&s duel runner and vance and hines 2 into 2 big radius exhaust. Would I need to get a fuel pak, or do some sort of tuning to the bike after the modifications?

To OP, it's a huge debate but my personal opinion is yes, you do need some sort of tuner. I could be wrong but it gives me peace of mind and that's all that concerns me.
Good luck...

if you change the air flow in/out on a fuel injected bike.... yes you need a tuner. the engine is lean already from the factory and soon as you make those mods it will really be lean. You could have some problems on your hand running it that lean.
I changed my mufflers out with v&h slip on's and it popped and ran really lean, put on a fuelpak and it ran as it should. the slip on's will dictate if you need tuner or not, the v&h straight shots are baffled but no back pressure plate like in the stock mufflers, so its a direct pass thru and that means you need tuner.

Welcome to the forum!
You will not "need" a tuner, but it will run better if you richen it up beyond the epa mandated factory tune.
The FL-XiED-10 will work well, better than the fuel pak, and less expensive. Or you can spend more and get a full fledged tuner.

Just exhaust - no
Just air - no
Both - yes
FuelPak will work fine, I am running it with my setup and I have more than just exhaust and air.
If you plan on doing more motor mods in the future, consider putting in a TTS, Thunder Max or one of the other tuners when you add more than just one of the above mods.

Personally, if its just high air flow intake and exhaust, fuelpak is all you really need. Stock ignition timing will be just fine.
Cams, bigger engine size, port and polish of the heads, decked heads, thinner head gasket.... THOSE are the mods that need a full tuner so a dyno operator can properly tune EVERY block of adjustable map.
