There could be so many things wrong, you could almost start anywhere. Have you shot it through paper....that will tell you alot�a cutout box and some newspaper will allow you an easy DIY at home paper tuning session. You could have multiple problems, or just one such the bow being excessively out of time, excessive cam lean, an incorrect nock level, incorrect arrow spine and length, is the rest set at centershot with the berger hole and are you torquing the bow badly? Any of the above can, and will, cause what your describing.

To start with, check the timing as it is the easiest to check. To check for timing on your bow, check the "window" on both cams (I circled the areas in question) and make sure the string is completely centered in both "windows" like it is in the picture.

If the string is not completely centered in the middle of both windows then your out of time and you will need to remove, or add a few twists in the string to bring the timing back in. Next, what spine arrow are you shooting? Over the internet, this is the beginning point.
