I am running an XS-T04S kit and an AVC-R boost controller. What duty cylce should I set it at when boosting at 1 bar.
Thanks for your help guys.

You set duty cycle to reach/maintain/not overshoot a seleted boost cycle. What you need to do after initializing and setting car type/throttle etc, is to set the duty cycle at ~70%. do a fourth gear pull, and see what your peak boost was. If you did not reach 1.0, then raise your duty cycle, if you went over 1.0, then reduce your duty cycle. do this until you find a duty cycle that reaches, and holds the desired boost.

Yikes! 70% sounds a little high IMO. The best way to set your duty cycle would be as Carl mentioned. After you are done with the basic setup, your last setting should be your duty cycle. Start at the lowest (20%) and bring it up until you reach max psi desired. Remind you that all cars (inclundig the wastegates) act a little different, so your setup may differ to someone who may have the same setup.
