Can't help too much with the tuning, but are you shooting the turnies at 74#( as in your signiture)?
I'm guessing 74# was maxed out and now it is not since you had 1/2 more turns in the top than the bottom?
My Pat had a terrible rip a week or so ago i couldn't cure. Took it to the bow shop- no adjustments and presto- pefrect bullets with both a 400 and 340 bemans. The only thing I could figure was the shops paper tuner is mounted high so you can aim square at it. I was lazy at home and didn't feel like stacking targets so i just set mine up to where I was aiming down. I hope that was it, I never rechecked once I got home

Glad to hear your doing well with yours!
