Just wondering if anyone has done the vacuum simplification with the stock twin turbos and had good luck with it. I was told that if you were keeping the stock set up, it is best to stay with the stock vacuum routing. Thanks....

 

There are plenty of people that have done it. IMO, if you don't have any boost problems, just leave it alone.

However, just do a search for "simplification" here in the 3rd gen forum, you'll get plenty of threads. Here are a few:

Yeap, I did it, no problem whatsoever.
It only eliminates the emission, it does not touch the sequential system at all.

I did most of it. Car runs better. Had some other issues done at the same time so can't vouch that it was the root but simpler is better
