BOV fitting

I needed to tap into my charge pipe for my BOV, it has two ports which gives a faster response preventing compressor surge. I was having a issue after 
installing the FMIC running 23 lb's of boost while shifting. Now it will vent as soon as I let off the throttle a little. It's an adjustable BOV so I can really fine tune it and it's working great.  

Couldn't find what I needed and didn't want to wait a week on shipping so all I did was find is a soft metal bolt and drilled a hole from the top through the bottom. I used 2 washers and a nut, cut a hole in the rubber coupling installed everything then added a small hose. Five minutes and it was done.

The top left is the normal vacuum/pressure port. The bottom port is pressure only and puts pressure on the bottom of the BOV diaphragm and makes the BOV react faster when the top port see's vacuum and allows more tuning.
