By tightening or loosening the forestry, you affect weather or lee helm. We had a little too much weather helm for my liking, so I tightened the forestay, probably reducing the forestay length by about 1/2". It doesn't sound like much, but it got my weather helm just where I like it (a little, but no more than about 1/8 turn of the wheel under most sailing conditions). Others may be right that the adjustment should have occurred at the mast partners, but I didn't think about it at the time. My point is that as others have said, forestay tension should be adjusted y tightening the backstay, but don't forget that it will affect weather helm as well.
