so all this talk about EGR and i tried unpluging the thing, instantly a better driver. like a new truck. lower EGT's and everything. but i hear some guys arnt getting max boost with it unpluged. is this true? i will soon be blocking it off completly. what all is happening when the valve is in the closed postion? is the hot air not getting to the coolent? any help would be wounderful.
Actually with the EGR valve closed, there is no exhaust getting recirculated back into the intake. You are still getting hot exhaust gas entering your EGR cooler, though. I have heard that you may not get max boost with it closed, but mine is closed with the SCT in my custom tunes and my EGR cooler has been blocked off.
