I am off to Willowbank tommorow with my VY SS and have been playing a bit with the Trans tune anybody have any pointers?
99% of the cars I have done previously have been manuals

Unlock/Release the TC in 3rd @ 90-100% TPS...

Lower shift times, pull as much TM as you feel comfortable with (dont know exactly what engine your car has, but my 4.2L I6 I run 0% TM in the engine and trans), do the TCC advice above, and maybe tweak line pressures up a hair (but do it after the rest is done, it can get hairy with LPs).
