After much thought I really think this tranny was specifially built for the 1/8 mile given how close the 2-3 shift is.
No the converter "tightening" did not go as planned and I wasted mine and a bunch of others people time f*cking with it not to mention a chunk of cash.
Thankfully I have always been fortunate enough to not have major problems with my cars but that one exception has always been getting the tranny / gear combo right.
Can't wait for Monday to get here so I can put a not so pleasant call out to the converter people.
