Yes GDE shutdown the EGR valve, You would need to call Keith and ask what % of time, the EGR cavity has a Thermo-coupler to measure the Heat and GDE tune must monitor the temp and if the heat gets to X level it will open But its rare it opens..again you would have to ask Keith at GDE for the details. I cleaned / Foam My intake 3 times until 41K Miles Both EGR and Plenum were replaced and I threw in threw in the towel, If your going to keep your 3.0 for the long term it needs to be tuned for DD use or it will suck up your wallet after AEM Warranty .
