My 07 street glide has 103 cylinders with polished and ported heads true duel exhaust not sure of the cam type and was controlled by a power commander 3. The power commander failed, my question is can a stock ECM be reprogrammed for the modified engine? any suggestions would be regretfully appreciated. I have limited funds to spend was leaning towards the power commander 5 at $360 through Denis Kirk

 

I am by no means an expert, but I dont believe stock ecm can be adjusted/flashed.
I may be able to help you out though,as I have a PC5 sitting on my shelf that I can sell cheap. No issues with it, in fact I sent it in to Dyno Jet to evaluate it and make sure all was ok with it when I first removed it from my bike.
Reason for removal? Motor build "out grew" it (adjustability), switched over to a Thundermax.
PM me if interested in it
