I'm sorry, I thought you had an adjustable fuel pressure regulator. If you're just running the stock FPR, your static FP should not be anywhere near 60psi. Start the car and let it idle, then pull the vacuum line off your FPR and see what reading you get on your FP gauge. It should be between 30-40psi. That is your static FP. If your FP rises above that when you boost, then you know your FMU is working, but since it stops at around 60psi, then your intank pump can't put out enough pressure to raise it any further. Any inline pump should be fine. Like I said, try looking for a used Airtex pump out of a DRAG kit if you want a low-buck solution.
