Has anyone installed a MBC on a set of newer twins?

"Note: On newer cars and turbos the restrictor pill may be replaced by a restricted vacuum line nipple on the primary turbo. If that is the case then you will need to "drill out" the nipple to reduce restriction. If you don't reduce the restriction you will not be able to lower boost."

What would this be drilled out to? & is it the fitting that has the 2 nipples on it for the primary & prespool?

Thanks.
