Muffler and A/C changed...
I just added Rinehart slipons and an Arlen Ness Big Sucker on my 09' Road King. According to the dealership, no change in mapping is required unless there is excessive popping and or backfiring upon decel. If that does happen, they suggested a change to the Power Commander.
I spoke with another dealership regarding this set up and they told me that I would have to have my ECM remapped to the tune of $150.
I've read sooo many different responses to this question, which is the correct answer.
Do I or do I not need to do anything else at this time?

I had my 06' FLHRCI upgraded to a Stage 2 right out of the crate (88 to 95) with V&H monster oval slip-ons and HD SE air cleaner and all I had was a shop remapping done and 31,000 miles later she starts every time and runs great. Some people feel like a Power Commander is necessary. I think the Power Commander is quite pricey...'course the Stealerships are pushing the PC.

The dealership suggested a Power Commander? Figured any H-D dealer would be pushing the SEST. I think many feel the remap of the ECM is all that is needed. I decided to do the SEST and couldn't be happier (although poorer). I'm sure you'll hear lots of opinions.

I don't know whose giving you info but I would say everyone here would agree that if you go beyond pipes (and even then if the pipes are too free flowing) to a free flowing aircleaner you need to richen that mixture up. First off to protect the engine from eating a valve, second to utilize to full potential of the upgrades.

you need to understand that HD engines are air cooled and in order to get by epa regulations they have to run the engines lean.
When you add pipes you are leaning the engine slightly and when you add the high flow ac you really leaned the engine. I suggest doing something. You are wasting power and a correct running engine.
I am using the pcv with auto tune and have used the fuelpak. The fuelpak is a lower cost to the issue and will do a very good job as long as you stay within the limits it can do. No cam changes unless you do a Hd 103 kit or stay stock with the engine.
The pcv is able to take care of any changes you do.
I do suggest doing something.
Either the PC111, pcv or fuelpak is easily added.
It took me 45 min. to do the fuelpak and 30 min. to do the pcv

I'd keep a close eye on the plugs as it is especially changing the air box out. Keep a eye out for a used tuner like I did and your bike will run cooler and much better for it

I have heard of Mufflers only and getting by without rejetting or the Map but never Mufflers and a high volume AC!

Well, I was finally able to take my first ride today after doing the Big Sucker install. I had the pipes on for a few days before adding the new A/C and they sounded great and I didn't hear or feel any issues.
I added the Big Sucker but couldn't ride for a couple of days because of rain. I was able to get out and do about 170 miles today and had no issues whatsover, in fact, the bike ran awesome. I noticed an immediate change in response and a slight power gain. I have not yet added a fuel management system, but I also am not getting ANY backfiring or popping on decel, just a nice gurgle.
I have an email into Jaime at Fuel Moto asking several questions and will wait to hear from them before acting on a fuel management system, but until then, the bike seems to be riding great.
I also have a good friend who is a Harley mechanic and he stated that with the 02 sensors, the stock ECM should compensate to a certain degree for the new slipons and A/C. He did recommend adding some sort of system, but also stated that the bike, if running great and not popping or backfiring, may not need any help.
Just sharing an update and looking for any comments or suggestions.
