To get in depth, you should first have your car tuned with the modifications you currently have. Then take your dynograph and determine what RPM range you are experiencing the most power. Now do some testing and determine where your RPM end up after shifting at increments of 500 RPM. Start around 6500 RPM and go up. Now, with that information in hand, compare your rpms to your power range. That will determine what the best RPM is that you should shift at that will put you in the most favorable spot for maximum power as each gear progresses. Do this for each gear! :thumbup:
