it needs a boost reference, not vaccum. The only vaccum source you have during boost is your pre-turbo intake, and that will not open a wastegate.

walter, are you spanish? As I read your bad english, I was doing a russian accent in my head. lmao!

Ha, I know, but try explaining that too him. Hook up a vaccum line to the WG, Walter.

I'm sorry. B16CRXT was right in telling you his way then. It will read PSI and MMHG (vacuum) though now with boost in the lines. Those "vacuum" lines do have vacuum in them and show vacuum until boost is created and there is now pressure in the lines. Any vacuum source will work because when the car boosts there is no vacuum and now pressure in the lines instead. I'm trying my hardest buddy to help you, I really am.

what I did was get a vaccum manifold from a guy on here named djfob. I put that manifold on teh brake booster line, and ran a good size line from it to the wastegate. But I had a turboxs dsmbc on that line as well to switch from low to high boost.

Run a line from the WG nipple to the Turbo nipple which SHOULD be on the turbo outlet. That will work just fine.

yep, you can do it this way too. But for accurate boost control, you should use a boost reference after teh intercooler. It's not entirely necesary, but you could be wanting to run 10psi, and only be running 8 or 9 once it gets past teh intercooler.
