What chip to use with a Supercharger?

[WickedDropTop]

I baught my procharger kit used and it does not have the chip with it. Would it benefit me more to buy a diablo or order the one that originally came with the kit from procharger? It is the stage 2 kit another question, can I safely run 10 or 12lbs of boost on my stock motor? I am going to have it tuned by JBA here in Cali. Also if anyone has any tips or pics of an install of this kit I'd love to see them as I am going to need all the help I can get
