Overboost issue post Dawes Valve and catch can fitment.

[BigRAWesty]

Can't say for the Tillix but the Dawes uses three ports Kallen. One for boost and two for the Vacuum side. If you are to fit a needle valve in then you use another T. And yeah I have plenty of needle valves in stock.....

But the actual valve is only 2 ports.. in and out ain't it?
