I don't feel you should need to at all. The EXHAUST is THE bottle neck on moving more air in and out, not the AC. If you liked how it ran, a different AC won't matter the least, because those ALL should be flowing more than a stock engine can use anyways.
This is NOT to say, that at some point, you should buy an actual tuner and have the bike tuned by a pro. THERE you would get the most power and bang for the buck out of anything you do/did to the bike. A download doesn't really do much at all.

It may not seem to run like crap, but even with the download it will still be too lean.
Get a real tuner, the bike will run cooler and you will get more power out of it.

What????? You're obviously new to the Harley world. Stock exhausts will flow more than enough for a stock engine, even with a Stage 1 air cleaner. Bottleneck lol....pure rubbish. Where did you come up with the bottleneck theory? OP...don't worry about it. The Stage 1 download DID bump your fuel enough to take care of the exhaust and air cleaner. I believe what I've been told and it's somewhere in the neighborhood of 5%. Plenty for your needs. Whatever subtle changes you make to either won't make a difference. Guaranteed you won't feel the difference. If you have a burning desire to go out and spend a grand for a tuner and dyno time that's up to you. BUT you won't feel it and would be better off keeping you money in your pocket. Until you get to a cam swap the Stage 1 download is more than enough. Don't waste your money getting caught up in all this "you need to get it dyno tuned" rubbish for a simple Stage 1 set up. As for a "pro tune" giving you the most bang for your buck theory...more rubbish. It's a simple Stage 1 set up. There is NO bang for the buck with a Stage 1. The gains are minimal and most can't feel it. If you think spending a grand for this unfelt "bang for the buck" is warranted...well all I can say is ....go for it.

wow.. way to open that proverbial can of worms there 2000FiveOh. Although not a professional tuner (are you?), I assure you wurk_truk knows tuning and doesn't provide inadequate or inaccurate information on the subject. The fact that the biggest restrictive bottleneck on these newer bikes is right there in the collector, is well known, and is well documented everywhere and the fact that a pro tune is a LOT more than a stage 1 download, tends to make me think your comments are "rubbish".
As far as spending a grand for a Stage 1 "pro tune"....money down the drain. Absolutely no bang for the buck. Look at some Stage 1 dyno sheets and show me where the 1000 dollar gain is. It just isn't there, especially in the rpm's most ride. Will a tuner dial in a few extra thing? Sure. Worth wasting a grand on...Nope. The bottom line is a Stage 1 add on is way over-rated. It just gives folks something to talk about on forums and at the bar. Performance wise, nill.
Thank you.
