got asked "how do the SHO ecu's deal with knock" - anyone know ?

I think at 5psi the tweecer was displaying low to mid 20's on my car and cruising it was in the mid 30's at 70mph.

where does the timing normally sit stock?

1 - 1.5 degrees per 2 psi of boost is a good starting point.

I use 1+ degree for 2 psi, but it also depends on how good your table of spark retard v. intake air temp is.
