Thread tension

I have a singer 111W157 sewing machine. I have bought and installed a new hook and thread controller. I have the hook timed well and the new thread controller in place per the instructions. Here is my question. I got a very loose bottom (bobbin) thread. following the instructions I loosened the bobbin tension and tightened the thread controller tension. The bobbin tension is as loose as I can make it. the stitch is now OK but My problem is that the stitch is so tight it looks like the thread is cutting into the vinyl is this right? Do you think the tension spring on the bobbin case may be incorrect. There is a definite drag on the bobbin thread when I pull the thread by hand. thanks for any help. David
