how do you properly tune a dual cam bow?

Is it a matter of adjusting your limbs or a physical adjustment to the cam itself?

this should help

Thanks for the attempt but I don' t understand anything they are talking about.

1. Set the timing as close as you can by eye? What does this mean. I looked at my cams and the only thing that I can find to adjust is the draw length.

3. Pull the bow into the wall as hard as you can. What wall?

None of this makes sence to me.
