I have a 2001 4.6 and I have read about porting and polishing the throttle body. Can someone send me the link on how to do this. Also what are some pros and cons of doing this mod???? I have the 1715 programmer this mod wont hurt that will it?

 

I do not know of any articles specific to our intake plenums and throttle body's but it consists of removing edges that restrict airflow. Here is an article where a fellow has some arrows that show bumps and edges that he will grind away.

You can also do some simple stuff like gasket matching...
