OK. New converter is in. Results are great. Drives as normal in "grandma" mode. Was able to lower idle to 900 RPM. MUCH smoother shifting into gear. Launch is MUCH improved when I stomp it. Should be really good once the carb is set up properly. Now, time for traction improvements...then, to the track!
