The good thing about it is that it has a screen and menu and is more user friendly, and it also has a paid upgrade to turn it into a flashpaq tuner (if performance tunes interest you).

The Flashcal/Flashpaq no longer let you adjust the psi threshold in the tires. (if you want to run your new bigger tires at less than the factory mandated psi, the dash light will be on). But you can still shut the system off. The procal allows you to adjust the pressure and also turn it off.

I have had two of each, and I like the simplicity of the procal better. (No problems with update issues or the crappy superchips support techs...)
