In my opinion it's worth it. I did the S.E. on my 2010 Wide Glide. I had Big Radius 2 into 2 on my bike and instead of a re-map I installed some Xieds. They were around 40 bucks for both if I remember correctly and they definitely made the bike run really good with the exhaust and intake. I would at least try them first since they are cheap enough and then if they don't work you can look into a tune later on. Are the baffles still in the Short Shots? If they aren't then I would get some in there. Otherwise, it won't matter much what you do to the bike, it's not going to run great with just short straight exhaust unless you plan on being in the 5-6k RPM range all the time.
