Hi - one comment I've heard about the new M-8 stage 4 kits is that the cams are very top end, low-mid range is vey much like the stock motor??? The stage IV S.E. cams have to meet EPA standards - so the valve timing is not optimal. I've got the 110 cu stage IV kit in my 2013 softail. I took the 259E cams out - went with a set of the Crane/S&S rocket cams - much better throttle response and low- mid range. top end made more power too. all-around better running. shop the after -market for a different M-8 cam? S&S and Andrews have new grinds. good luck!
