I ran mine for about 4,000 miles. found the only way to get them to run not topped out all the time was with about 8 psi. I also changed out the oil in them before I replaced them and that helped out some.
The problem with them is they do not allow proper suspension set up, its almost impossible to adjust any sag into the shock, and with only 2" of travel if you allow sag you dont have much left, so any thing that requires the wheel to drop into (pot holes, off speed bumps, small ledges) the whole bike drops into instead of the wheel dropping into it and the bike riding over the bump. The 12" shocks only have about 2" of travel , the 13" have about 2 1/2 (and that is why a lot of riders comment on the Ultra being smoother that the Custom) , and the dampening is slow / poor( can be slightly improved by oil change).
The good thing about then is their load carrying ability (like all air systems, thats why they are used in trucks and trains), more load add more air.
If your a solo rider under 250lbs and using more than 15 -20 psi the ride your getting may be smoother to you because you are not bottoming out, but you also dont have much suspension action (travel) going.
IMO the stock HD touring bikes are very comfortable and handle well and most people will never want or really need a different shock until they have ridden the same model bike with a better shock on it and then realize the difference that is available in both comfort and handling
