You will really need a dyno shift to tell you EXACTLY where to shift, but if you get a general dyno sheet from a similar car, then that will work.
I have always been told to shift right before your peak, because by the time you actually shift you will be right at it and that is where you need to be each shift.
Never shift into either of the ODs on the track if avoidable and it should be.
Oh and btw it is 6.5-7k or 6500-7000 rpms.
