chunked foam

I've gone recently from a 2wd stadium truck to a 4wd touring car. I've learned to tune my differential in my T4 by having them as loose as possible without slipping in accordance with my slipper. Now that there isn't on a slipper on my ta05-ifs, how should I be tuning my diffs? As loose as possible so there isn't any slippage? Would that cause me to "diff out" on a sharp turn?

Thanks.
