has anyone thought about taking some after turbo intake air from before the butterfly valve in the intake manifold and redirecting it into the egr tube where the exhaust gas would normally enter the egr cooler and then bock off the exhaust port to the egr. That way the egr system and sensors would continue to work normally and sense movement and pressure of air moving through it on the 2012 models......just a though dancing in my mind? The result would be clean warm air entering the engine instead of exhaust air and possibly no codes and no derate! It seems to me that when the butterfly valve closes this would create a significant pressure flow through the EGR system. Anyone out there with enough resources at hand to play with this idea?
