Take a look at this article, it explains the function very well. AThere is also a how to change the push pull ratio.
According to this i would be carefull changing the pull ( 20%) to push(80%) ratio.
From what i read, there are different LSD from Porsche available. The newer ones have a dynamic push ratio (from 0% up to 100%, depending on the load) so with one of these you would be fine in your pits and on the track as well.
Donīt know if yours is of the later type. But may be the articlel helps you to find out.
I found it very helpfull. Initialy i wanted to go for an ATB type Diff but now decided for a LSD.
Hope it helps.
