How can you tell if a Race Tuner has been installed on a bike without going to the dealership??? 2010 Ultra......

 

You can't.

 

If you did have a race tuner program downloaded on your bike you have been give a black box that act as the interface between your computer and bike. If you don't have the box then you may not have a race tuner. If you do have the box then it would take software and cables to connect to your computer and see what you got without going to dealer

 

Ask the orginal owner if the bike has one. If so and U don't have the box then U cant tune it and will need to buy another SERT..
