bad regulator or pump? Well this is a Bosch 044 external pump and an aeromotive regulator if im not mistaken.
On the dyno the pressure would rise along with boost (1:1 refrenced), start at 59PSI goes up to about 68PSI and then falls of about 10PSI (falls BY this amount not to this pressure)
Funny thing is, the BAP didnt seem to do a thing, and the pump along with a BAP should have been good to about 900RWHP if im not mistaken.
How do I know if its the pump or regulator.
Ill check for some other things as well, clogged fuel filter, tight radius bends on the fuel lines, but cant think of anything else.

Do have a check valve on the factory fuel line? Your car has oem regulators in the tank and will bleed off pressure to maintain the factory setting of around 58-60psi. This will cause the problem you descibe when boost refrencing.
Also, a single bosch pump+bap to support 900rwhp doesn't seem possible, at least safely. What size injectors do you have?

Ya no way a single Bosch can make 900rwhp sounds like the reg. is functioning till the pump runs out of volume. There are better pumps for your application give me a call I can help you spec out what you need.
