I dont know the actual fuel pressure, the main fuel system is the stock in tank pump supplemented by a second pump connected directly to the fuel rail that is pressure referenced to kick in at a certain point usually around 2-3lbs of boost pressure.
I would not know how to read fuel pressure when you have two fuel systems in operation. I do have a light mounted in my pillar gauges to tell me when the second pump is in operation.
The MAP sensor was calibrated to read the same as the stock sensor with key on and engine off. It took several tries but it is the same as stock in the last tune that I posted.

Thank you again,
Greg
