I never had the slightest issue even when I was running the T04E on a bone stock engine with a tired #1 cylinder. You are manufacturing a problem in your mind because it doesn't exist.
Never tried to drift it, just grip. It still has an open diff an it doesn't play nice if I pick up a wheel. I think it might do an 18 in the quarter, but I know it will go about 75 on the highway. It still scoots along with 800lbs of junk in the bed too.
Igor laughs at this contrived "torque" you speak of.
