First things first. Do you know what a dyno is?
In simple terms a dyno is something used to measure how much power is coming out of the car. There are a couple of ways that they work one style uses drums that the wheels roll up onto and then the car is cinched down to ensure that it doesn't move, the wheels are then used to rotate these drums and the readings come out in WHP numbers. The other type that I can think of off the top of my head is a hub dyno, where the wheel hubs are actually bolted to the machine and then a similar process ensues, once again giving you a WHP reading.
Now that that's out of the way. These machines are usually owned by shops that do tuning. The reason you want one is that by adjusting the cam gear and making "pulls" on the dyno you can determine the best offset (advanced or retarded) for the cam.
If you want to get further into it a chipped ECU and some tuning software would be your next step. If you are getting the car dyno tuned, the shop may be able to hook you up with a chipped ECU (or chip yours for you) and tune it for you as well. This will allow you or the tuner to adjust the fuel and timing curves to get the most out of your cam.
It is possible that you may be able to rent the dyno by the hour and tune it yourself if you fell comfortable doing that (it all depends on the shop).
The product itself will not come with instructions on how to tune. The manufacturers assume one of two things either (a) you have having it installed by a professional who knows what they are doing, or (b) you will be installing it yourself and you feel that you know what you are doing.
Straight lines are for sissies.
