I got a similar question going in the bowtech section, I haven't gotten any feedback though. Since you can't independently move the draw stop from the mod, I don't think there is much you can do. My question was if the edge pro mod would work on the regular infinite edge. Sorry really no help.
Something sure seems out of whack. The edge supposedly has a "full 80% let-off" which should be about 8 lbs for a 40 lb draw weight. 13 lbs is more like a 67% let-off. Have you tried untwisting the string also? This will increase the draw length, tho, so that may need to be adjusted. Are both the top and bottom modules set at the same setting?
