cyclerama 570 or the 575 will work great.

 

needs a little compression bump to 10.1 for those to perform correctly!

 

QtRacer had posted some results from the TTS100 cams in the HO 103 that he seemed to like a lot. I have also heard nothing bad about the cyclerama 575's either.

I know I will take some flack on this one but the HO 103's perform pretty well as is. The cam only bump is not a lot of bang for your buck. A few extra bucks and work the heads with a compression increase and the numbers become more justifiable. Again just my 2 cents.

 

I installed the TTS100's in my bike, '12 Ultra. If you want lots of power down low and an increase in MPG, you might look into these.

 

Mid-Range? What do you call mid-range? You have Andrews 48, Woods 777 which are considered mid-range cams. Many prefer the Woods 555, S&S 551, Andrews 26, plus there are other smaller companies that have plenty of followers.
Your question has too many answers until you are more specific in how and where you ride and what you expect.

 

Hey Kevin, I have a 12 Road Glide ultra,103, it is a heavy bike so with my wife and all the crap we pack when we travel the improvements you want is what I wanted. So I went with the Andrews 48 cam on the advise of the performance guy at Kutter's, now Boardtracker HD. I added the Dyno sheet so you can see what I ended up with. I am very happy with the outcome, it pulls like crazy, cams start to kick in at about 3000 rpm, I still get 40 - 43 mpg with momma and luggage, when solo about 43-46 mpg.

 

I had the Wood TW-222 cam in the RGC for a while. I would recommend this cam as a drop in for the OPs desired results.

Attached is the dyno chart from when I had the TW-222 cam in my bike.
