Had a Fuelpak on my wife's '09 Deluxe and Xied's on my '09 RKC. I like the Xied's so much I added them to her bike, now she has both and it runs even better than before. I talked with V&H tech support and they told me the two devices work on different parts of the 'band' and it should be fine. Just bought a Fuelpak for my RKC and will install on Friday, I'll report back on the results after this weekend...

 

I forgot to mention that nightrider gave my Bro a Military discount for the asking.
His is a 2011 Limited 103, air cleaner & V&H "superscrapers" ( x pipe) and ovals

xieds only work at lower end of the power range. once bike warms up, o2 sensors with xieds go open loop and the ecm just remembers the last closed loop values. If you make your own xieds using the old DIY instructions, for the money invested, the return is ok. but if you buy them preassembled, the costs of these things is too close to other more flexible solutions.

 

I have basically the same setup on my 2010 UC. I installed a 2009 cat-less head pipe, V&H Monster ovals and the K&N 3930 filter. I also have a PCV with 2 FuelMoto maps.(regular map & economap) Using the economap most times riding 2 up I can go 400km (250m) per tank. I've been tracking my fuel economy and getting 49mpg imperial = 42mpg US.

 

I recommend the Xied or the Vied...I've run them both and well satisified with them.

 

Running Revolution Performance EMS Tuner and so far, extremely pleased. For something completely plug and play, I don't believe there is a better system out there. Now if like me you want to tinker, you might want to look elsewhere. But I've run ThunderMax, PC3, Pc-V's with and without Auto Tune and I have to admit, my bike has never run so good until I put on the EMS system. My two cents......
BTW, I just went from True Duals to this Fat Cat and the system took a good 100 miles to learn the pipe and it now runs flawless.....

 

ran with Nightrider X14ied's before I went with the head pipes. Now running PC-V from FM. Getting about 50mpg highway and no heat, decel popping or ping. Noticed stock head pipes had some head dis-coloring - not sure if this was xied's or general issue - nothing now. Go with FM and you have options for future changes at no cost. Ride safe and often.

 

Looks like the XIEDS and the Fuelpak might a good system. This would still allow the 02 sensors to operate if I understand everything that I have read.

 

You are NOT going to get the bike to "run correctly" with the simplest fuel management system as there's a lot more to getting the bike to "run correctly" besides adding/subtracting fuel (unless you consider mediocre as the definition of running correctly).

That's exactly what you're going to be doing by adding devices that "trick" the Delphi system. There's certainly enough data and reports that should tell you that's the road your about to take (I think you even suggested you spent quite a bit of time chasing issues with another bike).


Then do just that! Or, access the ECM's map and change all the tables responsible for a well-tuned motor instead of adding devices, unplugging things, or splicing in other stuff.

Yes, lots of guys will tell you how great their bikes run with these tricks. But it's like listening to a guy that has always eaten rotten apples found on the ground...he thinks that's the way they all taste.

 

If I were you I wouldn't put that K&N into the stock airbox... I would get the Screaming Eagle Stage 1 Air Kit... You will get the most out of the pipes...

As for fuel management...

V&H FuelPak is the way to go if you don't wanna bother with it... You put in your setup online and they give you the values... you set it and forget it...

Thats my $0.02...
