My TDM900 came with a power commander, the question is how do I tell if it is set up or has any custom mappings?
Is it worth having it on an unmodified TDM900?
plug it into a laptop, you can leave it on the bike while you do this, then open the map and look at the map notes, if it’s been set up it will have the details of who did the work, if not then its a standard map from the dynojet database, if it’s a standard map the only way to check it is to have a session on the dyno, if you can’t do the above and if you’re local you could pop by our shop and i can check it for you ! 
Cheers for that mate, once I’m back on the road will have to come down and see you.
