While I am not an expert at the Cam and a Half tuning, I can tell you one thing for sure. GET RID OF THE FACTORY STRING!
The D75 material that Hoyt uses is pretty fast, but it never stops stretching. You can be assured that your peep will continue to rotate as long as you own the bow. Go with something like 452X. That material once set pretty much stays put. I have had a 452X string on my target bow for about 5 months. I would say it probably has about 5000 shots through it and my peep has never moved.

As far as the cam and a half tuning goes, take a look on Archerytalk.com. There are a number of posts buy a guy that goes by Javelena. He has some diagrams and directions on getting the Cam and a Half back in time.

As for the specs, you need to call Hoyt to get the numbers.
