So I have a full Graves system, Power Commander V, and dyno tune and was wondering if I wanted to change the slip ons would I have to get the bike retuned?

If you have a Power Commander V, do you know if if has the O2 sensor and auto tune set up . If it does then you can tune it yourself by using the auto tune feature .
