Heres a quick, super general guide to tire pressures:

1. Less PSI means more grip.

2. More PSI means less tire roll.

3. Play with them to learn what works.

4. When it comes to boxsters, count your blessings when the rear breaks away before the front at an autocross. It seems they all understeer like crazy.

You're tire pressures may be fine. However; playing with them helps to learn your car. Different weather and driving conditions will always make your car behave differently. As a SCCA national champion once told me "Even if your tire pressures are right, if you're not driving your car properly it may seem that they're wrong."

Best of luck,
