Default 2015MY Bike - V&H Short Shot Staggered

Hi,
Intending to order some Vance & Hines Short Shot staggered in Black - expecting them to arrive before I pick up the bike next weekend.

I notice that the 2015MY bikes have a slightly different part number on the V&H website - due to different o2 sensors or something.

Anyway... is it still generally accepted that, even on the 2015 bikes, if I am replacing the entire stock exhaust system with these V&Hs that I will NOT need to change the fuel mapping?

The dealer said that if I used slip ons then no, but if I replaced the whole system then it would need remapping.

I assumed it was generally accepted you only needed a re-map if the pipes AND air cleaner were changed?

Don't want to run too lean and drop a valve

Also, would it be better to run the bike with the stock exhaust for a few hundred miles or can I just put on the V&H when the bike will have literally 15 miles on it from riding home?

Well, I've put slip ons on, and it runs fine without a remap. However, my slip ons don't flow much more than stock (I guess; they meet type approval, so I expect that they can't do).

I've read where people have said that it's OK as long as you only replace the pipes, and don't touch the a/c.

Well, there's no absolute correct answer to your question, there's only opinions. And you know how opinions are, everyone has one.

My personal opinion is that a Powervision should be the very first mod you make to your bike. It lets you take control of your EFI and tune the bike properly, and has tools to help you do it. The ability to tune properly will improve even a bone stock bike. Plus, as you make mods, you'll be able to tune it as you go. Plus you get a lot of other cool functions beyond just the ability to tune.

You have to understand, the ECM has an understanding of the airflow through the motor, that's programmed into it. It's actually a model of the airflow, it knows how much air is flowing at every throttle position and rpm. It calculates how much fuel to inject based on this information.

When you make any change to the breathing, you change the airflow through the motor. This is especially true of a pipe change. And it's not like it just linearly goes richer or leaner. Some places in the airflow model, you'll get more air, other places you'll get less. It's the nature of an exhaust to pull and push back at different rpm's, and different exhausts behave differently in that regard. So take your airflow model and scramble it when you change the pipe.

Personally, I wouldn't want my EFI to have an airflow model that's different than what's actually going on. So I'd buy a tuner that let's me do it correctly. But that's just me. You'll find plenty of differing opinions. But that's all they are, just opinions, there's no definitive answer to your question.

Another opinion of mine is to skip the Short Shots and get a performance pipe instead. But again, that's just me.

I have a DynoJet Power Vision I use on several bikes currently.
(1) 2014 XL1200V --> Python Slip-ons Only
(2) 2015 Street Glide --> Vance & Hines Slip-ons Only
(3) 2014 Switchback --> Vance & Hines Slip-ons Only
(4) 2014 Wide Glide --> S&S Stealth AC and Cobra Speedsters Short Swept

In each case adding the powervision has helped with even the slightest issues. Mainly decel pop, lag in throttle response and fuel mileage.
I like the sound of a finely tuned and running motor.. that's the music to my ears.

And in "My opinion" I would rather know that all things are running as efficient as I can get them to prolong the life of my motor and riding experience.

Just my 2 cents...
