So my Bike is a 2014 Ultra Classic. I have added Rhinehart slip-ons and just picked up a de-catted head pipe. The guy that does the head pipes welds a chamber divider in place where the cat was. he claims a 12hp increase with no tuner. I think the bike still needs a tuner to add more fuel, so as not to go too lean.


I have been in contact with a guy from superchips about the vigilante tuner. He says the bike will never run right with a de0catted head pipe. Any thoughts or experience on this situation ?

 

It sounds like to me, he wants to sell parts (head pipe). I have a '12 SG w/ decatted head pipe and I used the powervision to tune it. It runs like a champ.

I think the divider plate would make it better. especially for autotuning.

 

OK, so after some more research, I decided to go with the Nightrider FL-ViED-10 set up. I'll see how it runs with this set up first. No reason to throw money at it unless absolutely necessary. From what I've read, this should do what I want.

 

I have a 2013 FLHTK with stock mufflers, decatted headpipe and stage 1 a/c. I am running the Fl-XIED-10, no tuner. Runs great. I was using the Fullsac 1.75 cores and also ran fine w/o a tuner.

 

Running a 15 limited with decatted headpipe, V&H FP3 , Arlen Ness intake Freedom exhaust. Let the tuner do its thing and runs like my ex wifes lawyers coming for it.

 

I have a 14 Ultra Limited, decatted headpipe, Reinhart slip ones, stock air cleaner. Runs cooler on my wife's foot and sounds slightly better. No tuner or flash. No problems!

 

I'm sure he meant to say it won't run right with a stock de-catted head pipe

Vance and Hines reports the Auto Tune feature will not work accurately on their tuners due to cross talk between the O2 sensors on the stock "de-catted" header pipe so this guy is just confirming what they say. Can you ask him why please? Every time I post this issue about Auto tune and the FP3 not working on sock de-catted pipes. I get blasted (owner pride and hard headedness mostly) by everyone and his brother about how it worked on their bikes and its just a case of Vance and Hines trying to sell me something I don't need. It would be nice to have independent conformation. Thank you

Aloha...Mike
