Thanks for the info...
Yes, the Challenger is a 70# bow.
I have had the cam timing checked, and actually found that the bow was out of tune.
I was able to improve from 212 fps..to the current 224 fps I am now at, by checking the timing. I am also planning to take a look at possibly upgrading the original cable and string on the bow, and am also considering to change the standard cable slide to a Bomar Teflon slide. I currently apply a light "grease" coating to my standard plastic slide.
Thanks again for your help.
