Does anyone know the PIS range (i.e., 4.6-5.4) on a CC Gransport and what they imply (i.e. are lower or higher values better for: (1) quicker shift speeds, (2) less clutch wear etc).

PIS values.

Well the intended window for PIS values should be between 4.8 to 5.1 on Gransports/coupes. Although Gransports respond best between 4.5 to 4.7 these values give you faster shifts and quicker clutch engagements also may reduce clutch slippage. Are you located in So Cal?

Thanks MC12Dave, thought that was the case as changing my PIS settings to 4.6 recently has made me notice faster shift engagements. To answer your question, yes I'm in Socal.

PIS=point of initial slip

When I had mine adjusted, it gave me earlier pickup and less slip. The car feels good now.

I think if you go too far, you can get stalling.

If you wanna see real improvement in shifting, buy a DBW.

What is a DBW?
Drive By Wire Enhancement Module They are made by Formula Dynamics. I love it and highly recommend it. There are many, many threads here about it.
