O.K.,
Hope he gets it right.
I'd personally stick w/ the stock configuration w/ al the pills in the correct location, until i had an mbc anyway.

That is the stock configuration except that he has it going to the BOV as the pressure source instead of the turbo. I suggested changing that one fact, but the diagram is still the same as stock. The intake line from the BCS doesn't do anything.

I could be wrong, but are you guys sure that using the pressure source from the bov line is wise?

The way I see it is this: Boost helps keep the blow off valve closed, now if you set up the boost controller to use the bov line that would cause a boost leak.

Now it is safe to assume that boost controllers work by bleeding off pressure from reaching the wga. If your bleeding off pressure from a source that is supposed to feed and help keep the bov closed, then the bov will not be able to do its job correctly. What your doing is similar to punching holes in your vacuum line that goes to the bov.

Yes, it does work this way - many people do it, including Buschur on all his cars.

Regardless, we've suggested many times that he use the turbo as the pressure source. I've said it 3-4 times myself.

My mistake, I thought that is what he was trying to hook up.
