I shrunk the port by like 20 to 25 percent. so you would think 20 to 25 percent more air velocity ... Wrong. like 1000 percent more. Before there was NO air in the port I could put my hand in it felt nothing and inside the box felt louder as well as metered louder. I didn't have a chance to throw it on the meter again today so I just used my hand. Now instead of putting my hand in the cab and feel the same and in the port the same and in the box a hair louder. now cab normal.  port tons more. and in box hardly anything. I am honestly shocked that little reduction makes that big of a difference. I guess when you start to go over on port it is a VERY weighted scale. a little over makes a big difference. thanks again</p></blockquote><p></p>
