I have a question regarding a certain type of setup. I have a 2009 Ultra, 96" engine. I want to know the feasability of replacing the cam with the H.O Cam for the 2015 103"s. I know the cam is similar to the 255, but slightly milder (easier on the valve train as a whole). Using this cam, would it be worth the upgrade to 103 pistons as well? or would this be a good enough effort in the 96"? Also, I have a HD tuner for this bike, the orange one that is "married" to the bike (SERT?). I do not know much about it but I am assuming HD has canned maps for each one of its SE Cams that can be programmed to this orange box, yes? No? I was figuring the box could be uploaded with a map of the 255 which would (my guess) be close enough to the new HO cam. I know the dyno thing and all that would be the preferable way to handle all this but that would come later in the game. So.. Is this idea feasable?
