Car has only had three race meets, first meet was spot on, then was crap thereafter. I then noticed the front belt was very loose.
After tightening the front belt and loosening the rear, the car seemed great again.
I hadn't changed anything from the first race.
So I am wondering now had the belt stretched. I race 13.5.

A tiny bit, the belt cam settings on my BD7 have not changed since new
This is running mod & and stock
I set the belt tensions when new and haven't had to adjust them since, it sounds like maybe you hadn't tightened the bulkhead screws down and the cams may have moved, I did that after changing the diff and being in a rush I had forgotten to re-tightened the screws
It may also be possible that the upper deck has moved from a shunt, in this case the belt tension could change significantly
