No matter what i do the FFB always pulls to the right. <iframe width="560" height="315" src="" frameborder="0" gesture="media" allow="encrypted-media" allowfullscreen></iframe>
Have you tried inverting force feedback? You can find it in Force Feedback settings, second option down.
I remember having a couple of similar issues, not sure if it was with R3E at all. If I remember correctly in one I had a game pad and a wheel both connected. Disconnecting one it solved the problem. In the second case I was using the wheel as a mouse as well and it did give me problems.
We sometimes get that when trying wheels not yet officially supported. Inverting FFB like @PaladinUK suggests solves the problem most times.
