I have a 2002 7.3 PSD and I have tried Superchip, Diablo, and Edge controllers. The Edge is by far the best in my opinion. The Superchip did not have impressive performance. The Diablo created huge clouds of low boost smoke, but did have good performance. If you are a techno junky then the Diablo has some nice features to interface with your laptop, although there technical support is horrible. The Edge has awsome performance and generates very little smoke, unless you really put your foot into it. I have heard a lot of different opinions but in my opinion the Edge is by far the best.

I second the EDGE vote. The newest revision is tuned well enough that it can be left in the 100hp mode, with no adverse drivability issues. Plus a great and accurate 0-60 and 1/4 mile timer. Also has a neat Data Stream that allows you to see Engine Oil Temp, Trans Fluid Temp, Trans line pressure, and Exh BP.
