Did you ever post a Dyno sheet?

What is the actual compression of that engine?
Thought you were looking for the "sound"?
The S&S .570 set at 10.2 cr should have good snap in a 110".
Done enough to know.

My 110 is set up like Scott says, and it's everything I expected. Lopey, torquey and less heat. I enjoy it no matter what gear I'm in. Tuning for this cam is key tho.

It does sound good and has snap going through the gears but it just doesnt hold 6th very well at 70 pulling hills. Its my own fault for worring about the sound

Ever thought about pulley swap or a Rivera Primo Game Changer, if you're doing a lot of mountain riding then a gearing change would be a lot more bang for the buck

Even FM will tell you their tunes are a starting point.

There is NO substitute for a proper dyno tune, and target tune can only "hold" a tune if the map is not optimal for your bike target tune will not correct it, it will only hold the values in your map

Better tune, use 5th gear pulling hills, especially on a bagger two up.

10.2 compression, and an actual tune.
Combination we build often.
Runs very well, but at 10.2, and with an actual tune in it.

As stated by Fat11lo, get a dyno tune but before you do get rid of the 3.15:1 gear ratio... Not good to lug up hills.
