there is a bung that is welded onto the side of my AEM, I really didnt pay much attention. But now it is on the car and I was looking over everything before I fired it up and that is open... what is supposed to go there?????
I figured it out after talking to dave. I was thinkin it was for the PCV valve but because the hose was so short, I figured I was wrong... but I wasnt. So I plugged it and put a breather on the PCV valve. Thanks!
