In the spring I'm gonna bolt on the Supercharger Kit from an 2007 SS parts car I stripped. I want to install the Stock SS analog boost gauge. 1. Is this guage retarded, and should I get something better and more accurate? 2. Does anyone actually have the wiring plan for how to install...

Ive been researching them and I found one Im considering. What do you guys think? http://www.performancechiptuning.com/Electric+Supercharger+5+PSI+Vortex/10/ Also since it generates boost, can I get a boost gauge?
