Correct me if im wrong, but the pressure before the intercooler and after it should be the same. The job of the intercooler is to reduce the temperature of the hot compressed air coming out of the turbo, if it releaved the pressure too, it would undo the work of the turbo and render it pointless to have one in the first place.
