Just out of curiosity, I recently found myself researching what the PR25DD engine could handle in terms of power and looked up the weak spots on the engine. , stated that one of the ways owners experience unstable engine operation is the EGR valve becoming "contaminated". This lead me to look up what an EGR valve is and so on. Since an EGR valve recirculates a portion of the exhaust gasses back to the combustion chamber getting in the way of fresh oxygen, would it be theoretically possible to gain more power by just simply removing the EGR valve all together?
