Track tire pressure with MPSC's on 997GT3

Any thoughts on target HOT pressures with these tires. I saw a post on Renn. that were much lower than I used on the 996GT3 with PS2's.

997 GT-3 Michelin Tire Pressure

Michelin advises that you start Cup tires at 25/26 psig cold, after a few laps on the track they should be in the 34/36 psig range.

Any thoughts on front to rear bias?

It probably needs adjusted to the conditions, the track (high speed or low speed turns), and driving style. Your best off to just do your own fine tunning.
