Steve- With F430 wheels and tires, I would run F430 pressures as a starter. Raising tire pressure makes the ride worse, not better, and handling on these cars is best at a tire pressure that keeps the whole tread on the road. Underinflated and the outer parts of the tire are more in contact. Over-inflated and the center of the tire tends to contact more.
Like John said, 32 psi F, and 35 psi R is where I would start, translated to Engish units, for an F430 with Michelin tires.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
