			Try a different fuel pressure gauge.  A Boxster normally varies between 3-4bar (40-60psi).  It is more likely that your gauge is reading incorrectly than you have blown out 2 fuel pressure regulators.
 As to your other symptoms:
 Any CEL error codes?
 Model, year, mileage?
 Any recent repairs or mods done?
