well i sent off my converter to have it updated with the new ats shark tooth stator. wow is all i have to say what a d/f like night and day from the old ats converter. the fluid coupling is much better without a huge rpm drop when locking up in od. that tells me improved efficiancy. now there is no reason to have a lock-up controller unless i want to lock it up exteme pulling. that is why i also installed billet shaft. all said and done i am satisfied with the way ats handled my problem and will finally say the new tq tiger tooth converter is worth taking another look at. also transmission guy improved my shift points. . i am happy to be back in the white beast thanks.
