Makes sense to change the shift points to keep them in line with the engine revs.

But changing the tcc isn't necessary and makes the lockup just wrong. (for example, going from 2.73 on my used pcm to the 3.42's in my stock rear, put my tcc points way low, tc was locking up and the car was bucking at 30mph at 1200rpms...)

It was easy enough to copy the stock tcc table back over, once I figured out what had happened. But it would be even better to leave it alone in the first place.
(or make it an option.)
