Honestly, I'd rather install it myself. There isn't a shop I know that I would trust. Plus, if the kit can be installed with hand tools, I don't see the point in spending $800 more just so someone else can get their hands dirty (and bust things in the process). If I install it myself, I can take my time, read the instructions and follow them carefully... something a usual shop guy wouldn't do.

I can just hear, "What? Supercharger? Oh yeah, no problem. Piece a ca... ut oh. Uhhh, you don't need that. Just an extra part."
