Lot's of good reading there. Lot of good info on how capable the stock ECM is also. As long as you stay with the stock headpipe, cat or no cat and stage 1 Air filter and slipon's, the xied's will work fine IMO.

I put them on my stock 2010 StreetGlide. Honestly couldnt tell you if they "work" or not. Still running them assuming the engine is "cooler" but have no idea. Its always hot when I touch it!

They work !
I have the older 02 IED's on my 2010 FLSTFB, with the Bassani Road Rage Long w/Quiet B. stock AC No stage 1 download, and yes it is still Hot, but not as bad as it was with the stock exhaust w/cat.
AFR is 14.2

Call the nightrider guys and they will give you the straight talk about how/why they work.

+1. I have 'em on my 2011 FLTRU and honestly can't tell a difference with the "butt dyno." Engine heat seems the same too. I'm keeping them on for peace of mind (placebo effect?). I don't like how lean the stock ECU runs so I'm hoping this richer mixture helps prolong my engine's life.

I have some ASE training.
My 09 when stock had a slight pinging problem under certain riding conditions which was repeatable.
XIEDS solved that, making the mixture slightly richer.
With that, I was able to add hi flow exhaust and intake and retain good function.
they are a simple solution to a sometime complex problem
MPG maybe dropped from 44 to 43, they cost about $125 shipped, and they offer a Military Discount ( which my Bro got)
