Tire pressure?

[ViperGTS]

What is the recommended tire pressure for the new PS2's?

18" - GEN-II stock size tires.

And,...
what do owners use? Why, if different?

On the 2008 Viper which have the PS2 as the OEM tire, Dodge specifies 29 psi cold for all tires.

For autocross events, I have run the PS2s at 34 psi front and 30 psi rear cold;

For driving schools on a road course I have used 33 psi cold for all tires which worked really well.

The Gen II PS2s are a different tire design than the 2008 PS2s (C1).

The 2008's have a stiffer side wall. I run 29 psi cold all around on the street. You may want to increase the tire pressure a bit for auto X or track events. Kinda depends on the track conditions, temps, how fast / aggressively you drive, the way the car feels, etc.
