I've done a bit of research on it. They've made modules for other vehicles and had extensive problems with reliability and product consistency. Search for their other products.

Also, based on how their other products work and the install location on the CRD, it appears as though all their product does is substantially increase the line pressure in the fuel rail on the engine. As discussed in the latest issue of Diesel Power Magazine, such devices can cause leaks and premature injector wear/malfunction.

I'm thinking we probably best wait for more tested solutions...I hear Edge is coming out with something soon.

Incidentally, if you look at their other modules, make sure you look for Dr. Performance Predator. THere is another company that makes a Predator module that is totally unrelated (and works relatively well, from what I understand).
