Has anyone figured out a shortcut to remove the EGR valve on a 3.4 without an SES light?

Not to be a dick, but the seach only yielded me an EGR removal solution for the 3.8 liter, which uses a linear EGR system. It is designed to accurately supply EGR to an engine, independent of intake manifold vacuum. The valve controls EGR flow from the exhaust to the intake manifold through an orifice with a PCM controlled pintle. During operation, the PCM controls pintle position by monitroing the pintle position feedback signal. The PCM uses information from the engine coolant temperature sensor, Throttle position sensor, and the mass air flow sensor to determine the appropriate rate of flow for a particular engine operating condition.
My 3.4 liter uses a Digital EGR valve. It is designed to control the flow of EGR independent of intake manifold vacuum as well. The valve controls EGR flow through 3 solenoid-opened orifices, which increase in size, to produce 7 possible combinations. When a solenoid is energized, the armatture with attached shaft and swivel pintle, is lifted, opening the orifice. The digital EGR valve is opened by the PCM quad driver, grounding each solenoid circuit individually. The flow of EGR is regulated by the PCM which uses information from the coolant temperature sensor, throttle position sensor, and manifold absolute pressure sensor to determine the appropriate rate of flow for a particulare engine operating condition.
They work different, and I can't get it to quit throwing codes. I know this mod is illegal, but it's not a daily driver, it doesn't see the street. Thanks for the search suggestion, but I was hoping someone had a solution to this problem.Teal 94 Camaro 3.4 Liter<br />Transgo stage 3 shiftkit, Shift module, corvette servo, SLP cold air induction,3.42 ring and pinion, Heavy Duty Posi LSD, Flowmaster exhaust, NX, blackouts
