I've been using one from cartech.net for a couple years
now.  http://www.cartech.net/fuelaccessories.html

It was around $200, but I've heard from some Dodge turbo
guys that if your are, or know someone in the automotive
business (shop owner, manufacturer, re-seller, etc), that 
they can get it for around $150.

They have several models, including a new, more expensive
billet model that looks quite a bit nicer.

They go into the fuel return line *after* the stock fuel
pressure regulator.  They are adjustable in the onset, and
in their rising rate from 1:1 to 7:1 (or maybe 5:1, don't
remember).

The onset means you can start the fuel pressure boost at 
around 2 or 3 inches of vacuum, or 1 or 2 psi of boost.
The rate sets how fast fuel pressure comes up relative to 
boost once the onset point is reached.

Onset is adjusted by screwing in a stud.  Rising rate is 
adjusted with an adjustable bleed of the boost sense line.

Works very well.
