The timing belt on the 968 is not adjustable for tension - there is an automatic hydraulic tensioner for that.

The balance belt is still 'manual' like the 944 and most people set (incorrectly) them about as tight as the timing belt when it should be much looser. The balance shaft belt runs very loose actually...too tight and it whines like crazy. You should be able to grab the long span of the belt between the upper balance shaft gear and the lower tensioner and twist it between your thumb and finger 180 degrees on itself and no more.
