Do you have anything to actually measure the tension of your racquet once it is strung? Also, do you think it is a mechanical problem with your stringing machine? If it's an older machine it may be time to check the nuts and bolts, make sure everything is tight and in order. If you can't pinpoint it then I'd suggest setting your tension lower than usual since it seems to be above the tension you'd like and see how it feels.
