    Seeing if anyone may be free to assist me in trying to find my damn vacuum leak. I have overtime Saturday and Sunday but I should be free after 4pm both days.

    It surges when cold on start up, also my boost gauge climbs a bit in vacuum. Meaning the needle goes from 20 to 17.

    Sure it's not the idle air control valve?

    Well my mechanic friend is out of town and I haven't had any luck, I'm willing to buy some food/beer (or whatever your vice may be?) for anyone who's willing to give me a hand. Trying to get this done soon before I put in my parts.

    Have you checked all of your inter cooler connections? Most likely its a vac line leak get out the soapy water and spray all of you connections.
