i have a SE race tuner i bought just before they were pulled..
my question is this
a friend has an old (2008) pro street tuner. i am wondering if my software will run his tunner or if it is dedicated to my tuner only

 

Year and model of your bike?
If the tuner was set up with the bike, it is married to it. As for software, that really just a file so I don't seen why you can't use the same map. I think that all you need to do is copy that map from your tuner and install it on his. I know how that works with my ThunderMax but can't tell you how to do it with the SE tuner.
