Thats the vacuum pipe for the DV. I moved my DV onto the throttle body hose as is colder air (or meant to be) on that pipe as it is after the ic.
Which pipe are you refering to? The thicker blue one running along the front of the bay or the black TIP pipe which leads to the airbox?
so if the thin one keeps falling off on mine as it is not secured i would be loosing boost?
Just get a tie wrap on it and yes it will be causing a problem.
