Not that I want to propogate such a lame argument, but I thought I'd point out the fact that noone is copying anyone's supercharger kit, or, more correctly, they are all copying each other. However you look at it, none of the respective companies are utilizing a supercharger that they've developed on their own. ERT, Dinan, and RMS all have used Powerdyne blowers in the past. Now, RMS, ERT, and ESS are all using Vortech's V2SQ. So, considering this, the only differences, such as bracketry, and programming will not ultimately change the output of the system. The V2SQ blower is capable of producing 20psi, no matter who is selling it. So, cranking up the boost is easy to do, and that's where any difference could be had. Sure, programming will change it's efficiency, but all things being equal, our cars can't handle beyond 8lbs at the factory compression ratio very well anyway. So it doesn't really matter who's kit you use, just as long as the bracketry is well designed, tubing is well placed and designed, and programming is correct.
Peace,
