I stand corrected 58 psi is your average FP around 32-35 lbs, and its about 51 at o psi. I was referencing the number originally at 0 psi boost, but since your FP setup is not normal, i guess nothing "normal" applies here looks like, I'm learning new things everyday from your car. I sense your attitude towards my comments , are really not appropriate , as all you had to mention your setup does not work that way, and I would have understood this concept. Enough said I'm going back under the car to keep your blood pressure down for now anyway_O
