Thanks Don, I bought a Vaporworx PWM for my LSA Camaro build (in progress). For my LT4 swap... All the wire harness vendors are saying "you really don't need it, we very seldom include them in our harness". My understanding is this..... with a supercharged motor, the fuel pump (ZL1 pump) will put out a constant 70 psi, regardless of fuel demand. The PWM, will dial the pressure down when the 70 PSI is not needed, hence reducing the load on the the fuel pump, extending life, cooler pump temps, etc....
