Are you sure that the limb is twisted? Or is your cam leaning? If it's the cam leaning.. then the bushings are prolly worn out and need replaced. I work on alot of PSEs.. and if I have any issues they are great to deal with. If the limbs are indeed twisted.. I'd think that PSE would replace them free of charge. But you will need to take the bow to an authorized PSE dealer.. and let them look it over 1st.
