The factory fuel system is modified with an additional fuel pressure regulator that raises fuel rail pressure in proportion to the positive manifold pressure. The factory intake manifold is replaced with a new manifold housing that contains the supercharger and intercooler assembly. The EGR tube inside the manifold is modified to ensure even distribution of gases into each cylinder. The factory electric air injection pump is relocated to the inside fender area. Maximum boost pressure is 7 psi. The C class models receive a voltage step up device for the fuel pump when in the boost mode. A 500 ohm resistor, designed to prevent a lean condition during high RPMs, is installed inline with the output signal of the mass air flow meter.Vehicles which have been certified to a Ultra-Low-Emission Vehicle (ULEV) and/or the Supplemental Federal Test Procedure (SFTP) standards are excluded from this Executive Order.
