ok so it sounds as though the new x2 is bringing in some happy people and from what I gather you get everything you need with it minus a pyrometer or a commander

If I did just install a pyro what options would i miss out on?

 

Trans temp I think. The switch that comes with the X2 reads boost, rail pressure, and ECTemp. The commander is nice, because you can set up some safety parameters when you beat on it a little too long and you can see upto 4 parameters on the screen to view. I like mine.
