Quick question, how does a bigger or smaller pulley effect my superchargers? I don't want to run too much boost but I want a good kick...Also is anyone familiar with how to hook up the psi gauge?

I have an Edelbrock Mechanical fuel pump in good condition. Stats :110 GPH 6 PSI and supports up to 600 HP...I want 65. PM me if anyone is interested. heres a link to read more about it....http://www.summitracing.com/parts/EDL-1725/ or...
