ChargedSS Posted April 19, 2005 Report Share Posted April 19, 2005 '03's seem to be mechanical driven as far as boosting the fuel to drive the 42LB Injectors that come standard with the Radix Systems and what we procharger guys end up installing after the fact. The '03's need to have some form of fuel pump assister (In essence, a 2nd fuel pump) either in line or in tank. The '04's seem to be more about the Manifold Pressure being sensed by the PCM and adjusting the system to compinsate to maintain the constant pressure needed. Has anyone had any experience in this, or am I going to Guinea Pig This? Quote Link to comment Share on other sites More sharing options...
