I agree but it hasn't been and issue on my combination. Just looking to make it more repeatable.

Gary.. your post said low RPM heavy car = bad for the convertor.. 8" convertor?? what if you go to a bigger convertor..like a 10"?

I know that I limit RPM on the starting line and use that setting as my stop RPM.. The 8" convertor goes 5800 but I limit it to 4400..

If you had lots of motor.. (like a lot of guys) do you really need a loose convertor?

I think shifting on time is more consistent. I believe time gets the shift closer to the same point on the track every pass. If there is a little more or less tire slip I think you will see less difference in the pass.
