Hello, I'm new to the diesel world looking for advice. I recently blocked my egr cooler and I have about 5psi lower boost pressure now, and as far as I could tell the power feels the same and I havnt noticed any exhaust or boost pressure leaks. From what I have read on other forums this is fairly common, should I be worried? Is there a solution or reason for the drop in boost pressure? Any advice would be greatly appreciated. Thanks
