UPDATE: I finally got a chance to drive the car. Prior to that I was taking my grandson's word for how it is shifting. The new governor is PERFECT! At light throttle it shifts @ 1800-2200rpm, right in the power range. At aggressive part throttle, shift points raise a few hundred rpm (2600-2800rpm), again right in the power range. I am confident if we needed full throttle acceleration, shift points would pop up to the right higher range.
In summary, the weight we trimmed as described above was perfect for our street setup.
