I had this same issue recently on a Mathews V3 after getting the strings switched out. I'm no bow technician in any kind of way, but I've been successful in setting up, and tuning my bows in the past. I was losing hair trying to get this bow tuned. To me, nothing was adding up. Regardless what I tried, or researched, everything had the same result. At the time I didn't own a draw board, and didn't put much thought into it because the cables were lined up with timing holes on the cam. Even the pro shop technician mentioned when I picked it up that he checked the timing. I eventually checked the ATA measurement, and it was a little long. So I purchased a draw board, and even though the cables lined up with the cam, the bows timing was slightly off. So I started twisting cables. Didn't work. I eventually pulled off the strings, and cables. Stretched, and twisted them back to factory spec lengths, and reinstalled. That put the bows ATA back to its factory specs, and it corrected the timing. Bow was shooting right again.
I was going crazy. This experience had me trying / doing all kinds of things that didn't make sense. I even started blaming it on my form even though I could pick up my other bow (hoyt), and get perfect bullet holes through paper.
Anyway, hope you get it figured out. That bow had me so frustrated, haha.
