    42 psi idle with vacuum at the regulator. 58ish with no vacuum. Drop it down. You might want to double check the gauge is working correct. Thats a CHit ton of pressure you have. I say the chugging your seeing when in boost is caused by this. Higher pressure=lower IPW's the injectors are opening shorter but over fueling
