Hey justnwynn, there is currently a thorough dyno test being conducted this weekend in another post that is answering many misconceptions in those areas. It has already been determined that the installation of the lumps, does dramatically improve the airflow and HP of these engines throughout the entire operating RPM range. So that idea of not to do it, is definately one of those misconceptions. Keep watching the post of this dyno testing, and im sure it will further answer other questions you have about how to properly modify and improve your current inline project.
