I have a 2014 FLHTK with about 17,000 miles on it and now I have the need for more power and better throttle response. I would also like to get things to run a little cooler. My riding season here in Nebraska could be over for the year in about 60 days then improvement season starts.
To meet my need for better performance I have roughed out the following plan for the winter. I would like to add a Vance & Hines FP3 to the bike with the little riding time I have left. Once the snow is here I would install a Vance & Hines power dual head pipe and their High Output slip ons. On the intake side I would just use the Screaming Eagle High Flow intake kit since I like the look of the stock cover.
Does this line of thinking make any sense to those more experienced in doing these changes? It's a substantial amount of money and I don't mind spending it if I only have to do it once. I want to keep some options open if I want to do other improvements in the future such as cams or whatever. I do have a connection that can get me a good price on Vance & Hines products and I hear good things about them so that's why I'm leaning that way. Any advice would be appreciated.

 

Since you're thinking mostly Vance & Hines, have you looked into the V02 naked air intake? Utilizes the stock cover too. keeps the stage one all V&H.

 

I recommend you contact fuel moto, tell them what your after and ask for their recommendation. They are a manufacturing/engineering outfit and specialize in performance upgrades. I have their 2-1-2 header pipe, jackpot mufflers and power vision with target tune and my bike runs awsome and heat has been greatly diminished.

No reason to upgrade the air intake on the new rushmores for a simple stage one. Or probably even a cam change. Save that money for a real tuner like PowerVision. And yes, call Fuel Moto..

 

You're on the right track, I did the same last spring except Twin Slash rounds. When you do the auto tune most suggest a tank of gas will be enough. I did that my first auto tune and then did another for almost 500 miles and got better results.

 

My 14 SG was noticeably more responsive , it also has the HO motor with a little hotter cams.

The FP3 is decent if stage 1 or maybe even cams are all you plan on , I wish I would have spent $200 more on the pre-mapped Power Vision from Fuel Moto. I originally de-catted my head pipe , FP3 , and an S&S stealth air cleaner ( Uses the stock and many other covers , vary reasonable price on ebay) and immediately noticed the difference.

Since then I went to the Fuel Moto 2-1-2 head pipe with the ceramic coating , heat is reduced even more , throttle response is so much better and I still get 40mpg.

My dealer said he can now dyno tune with my FP3 also.

 

How's the sound? I'm good with a louder deeper tone but I've spent enough on music upgrades and don't want to drown that out with an obnoxiously loud exhaust system.

 

I'm being ignorant here not an *** but what will the Power Vision do that the FP3 won't do for a guy with basic mechanical knowledge. I'm 150+ miles from a dyno and then I don't even know if they are worth a dam.

 

If you aren't going to dyno tune the bike, there is nothing the PV will do that the FP3 won't. Everybody has his own favorite, and some just like the PV better.

The PV has an auto -tune feature (add on ) that uses wide band O2 sensors that cover more RPM range than the OEM narrow band ones do. You can buy additional licenses for a PV so it could be used with 2 more bikes , FP3 is one and done. If you buy a PV from Fuel Moto they will give you free map support and additional warranty time.

Dyno tuning is more precise and will yield the best power gains for your individual set-up , even with the same components every motor can need a little different tweaking to get the most out of it , auto tune is cool and works to a certain extent but with only narrow band O2 sensors a good dyno tuner is going to pull more out of that motor. The key to a good dyno tune is the guy doing it.
