07' FXDC. K&N filter, Python slip ons, Stg.1 download. Got the XIED's a few days ago. Decel pop decreased by 75-80%...almost gone. Can't honestly say if she's running cooler but I would imagine so since she's definitely running enough richer to all but cure the decel pop. (And I live in Fl. and it's already 90 freaking degrees). Throttle response? Was great for me anyway but any change is definitely within the "just in my head" range. Only other thing is she sucks a little more gas, which of course, is to be expected. Over all, pleased with my purchase, and for a hundred bucks would do it again. And for what it's worth,(and this is totally subjective) I get a good vibe from this Nightrider guy who makes these things. This is the type of Made in the USA small Biz I like to throw my money at and support.....Nate

 

Well if you lost fuel mileage shes got to be running cooler! I wonder if anybody has one of those oil temp gauge dip sticks that bought these XIEDs? Would be interesting to test the oil temp before and after the install on the same day during operating engine temps!

 

Yeah, I know it would have been more helpful to have been a little more scientific when installing the XIED's. But you know how it is... U get somethin in the mail and three small children and a kitten are trampled on the way to boltin it on the bike...

 

Ya i hear ya!

 

I like hearing this as i am ordering mine soon!

 

I found pretty much the same with my new Xieds. My bike is totally stock. I feeling better throttle response and definitely feel it running cool. No data to back it up, just know what my legs is telling my on a hot TN day. Best $100 I've spent on my Dyna so far. Had mine for about a month. The first ride I took with them on was thru the Dragon, liked the extra punch there coming out of the turns.
