so stage one of the ESS kit gets the same power increase for a little bit more money:

but the stage 2, for almost 7 grand gets it up to 300hp (220kw)

What I dont understand is, what is the difference between these stage one and stage two components as they both have the supercharger in them, I assume if you upgrade to a stage 2 you sell off the stage one?
