There are tricks to do to the governor. The simpilest way to get the thing to get higher on shifts is to buy the governor mod kits such as B&M etc. Instead of creeping up on RPM points, start with the highest shifting set up and work downward if it's too high. Most of the time, the lighest (highest) will put you close to your mark. If not, there is a little additional trick from a ball point pen that will fine tune it up even higher. Try the kit first and see where it lands.
