It does, but in my experience they couldn't lower the fuel pressure at all, they were only able to raise it.

The problem with the B&M unit is that it still uses parts of the stock regulator. Once you upgrade the fuel pump the small fittings on the stock regulator are "overrun" which creates more pressure at idle and low boost. I have the same FPR on my Talon and I can't get my base pressure below 45lbs with a 255 Walboro. I too got mine for free but now I'm picking up an Aeromotive unit to replace this thing. This might give you a better explaination.
