I can just give you some info about timing the Nitrous Cam. The most important things can also be found in the bow manual provided with your bow.
In case of the Nitrous Cam you should check for the factory specs. If everything is correct you can check for cam timing. Draw your bow slowly until the cam rolls over. If the cams are timed correct you should be able to pull your bow into the wall without any hump or so. If this is not the case you have to look which cam rolls over first.
Keep in mind which cam must be tuned and get a bowpress if possible. Turn the limb bolts out or press the bow until you can take the string/cables off. Twist the cable which is connected to the cam one turn. Put everything back in place and check if the timing is correct. If not try further.
