less boost with an egr cooler delete, block off plate, dummy valve, etc is normal. when the egr system is in place and operating properly manifold gauge pressure will be higher then when there is no egr flow. its a complicated answer but basically the volume and pressure of the exhaust that is recirculated back into the intake manifold addes to the overall boost pressure.
