If you purchased the original NEUSPEED HP kit years ago, or are using another manufacturer's supercharger pulley without a fuel system upgrade, this kit is for you. It includes a boost-sensing pressure switch that enriches the fuel mixture at part-throttle settings. In contrast, the factory system can only accomplish this during wide open throttle. Our stainless intake T-fitting re-routes the idle stabilizer valve back through the intake tract to prevent the 2psi boost loss seen in the factory system.
