I had to add metal back to my governor. A set screw in the hole. Then I had to take metal out by grinding on the head of the set screw. It seemed to shift different at different boost levels.
You need to test it under racing conditions and not pump gas conditions. Mine shifts at 5800 at 21 lbs of boost but on the street it shifts at 5300 at 16 lbs of boost.
Do you guys see the simular shift patterns? I was thinking of leaving the governor alone and pushing more boost in it to see if I could tickle the rev limiter. More torque would push through the converter increasing the rpm of the motor but not changing the rpm of the governor.
