1- Need to get a dyno graph and use that as a base. (shift limiter)

2- Then go to the track and log a few runs under different shifting points and see what nets you the best times and those are your ultimate shift points.

Basically you want to shift at an rpm that keeps you in the highest average hp range between shifts.

dyno it as high as you safely can with your valvetrain, then post the data here.

This is why you dyno. First you raise the limiter till like 7000rpm
Then they do runs. If your cam range is like 1900>6300 so you'd shift around 6600>6700 so you can determine where power starts falling off. That point is usually very close to shift points.
Once your shift point are known, then 300rpm above that is your limiter.
