fl-xied-10
If you decatted Nightrider suggests 1/4.
I run the NON adjustable XIEDs and happy with them, super smooth, zero issues, NEVER a pop, nothing. You will not notice a huge change, they can only adjust to a MAX of 6% more fuel.
Im really not a believer in the adjustable (VIEDs) ones for the reasons you and others mention.

if you check their site, you'll see that some of the new xieds, such as the fl-xied-10s, are in fact adjustable. He could have been right in what he was saying. And also, regardless of whether or not I thought wrong in thinking I should be adding more fuel or not, they are advertised to work well on a bike with decated heads. They actually specify that. They made my bike run worse. I'm not saying they aren't for everyone, as each setup is different, and I can certainly say they add fuel as advertised, but they did cause my bike to run poor at all settings.

No big deal and the reason I posted what I did was to clear up confusion..
The FL Xied 10 is not adjustable.
The Fl Vied 10 is adjustable.
I have the Fl Xied 10 installed, non adjustable.
This isnt the fault of the product, you just were asumming wrong without any data, like from a DYNO. If anything the Breather and Slipons would cause a lean run in SOME engines.
If anything, removing the CAT on a stock Rushmore bike will lead to a possible slightly richer fuel mixture from the stock 14.6:1 to 14.3:1.
Nightrider actually will tell you if you decatt reduce the setting from 50 to 25 as the removal of the CAT will slightly increase the fuel mixture on its own, as once the CAT is removed more air gets into/mixes into the exhaust and this tricks the O2 sensor to add a bit more fuel.
I personally run non adjustable XIEDs on my bike but not for the purpose of, I think it needs more fuel, I did want to stop my lower right leg from burning, so the DECAT and XIEDs stopped my leg from turning red. In that respect it worked, I also feel a little less "stumble" at parking lot speeds and is worth the slight loss of MPG..
Other then that my bike is stock. I have unplugged them on a few recent trips, to experiment. Meaning half the trip unplugged and half plugged, the heat returned. SO they are plugged in. Anyway, the difference slight but its there and I will continue to play, heck, its why we own bikes!
BTW, the reason I chose non adjustable XIED is simply who am I to say without a dyno what a proper setting is? I figured they will do what I want or I wont use them.
The very most the XIED OR VIED can increase fuel mixture on a RUSHMORE bike is to 14.0:1 which is why I just went all the way. Anything inbetween is just guess work and I think in that case better for a dyno.
Well Cat or no Cat factory fuel calibration is set to lean cond to satisfy emission regs that cause motor to run hotter along with at times slight surge @ low load cruise ,soggy throttle response & not so smooth an idle too which is a good reason to install xieds/vieds or any other fuel enrichment device on our EFI HD's.
The VIED's i installed on my 09 with bone stock 96" motor corrected the slight surge it had @ light throttle setting & low load cruise ,fixed the soggy throttle response & not so smooth idle my bike had too which was great.
I found the 50% setting worked best on my VIED's.
