I was taking a close look under the new MAS pipe I insatlled from Buschur and I found this hose that
branches off in to two. Looks like its coming off of some junction box that has a hose that I split into
the BOV hose. Where does this go? Also, with the Profec B Spec turned all the way full bust I am only
getting max 19psi. Any suggestions?

 

Those hoses used to attach to your turbo housing and wastegate.

 

So can I just remove it from the little junction box or just cut it short and plug it?

 

The junction box you are refering to is the one in the red box right? That is the boost controller. What you should do is unplug the hose from there and plug it.

 

WHy would you want the unplug the hose from the factory boost controller? How does it get its source? If someone could explain in detail that would be great. Thnx. Right now I have the hose with the red on it T'ed off from the BOV. Is this wrong or????

 

You should have a Y there. One side (with the red color at the tip) attaches to the wastegate, the other side of the Y connects to the boost source after the turbo, The other end of that entire hose connects to the plug on the stock boost control soleoid (the plug closest to the cockpit) and then the other nipple on the BCS connects to a short VAC hose that connects to the turbo linlet pipe.

 

Maybe this will help

 

In the original post he said he has an EBC.

 

If you have a EBC just remove those hoses from the stock solenoid, they are of no use. How's your EBC hooked-up, you might have a leak? I have the same set-up as you, except for I have a MBC-

 

I swapped the 1G BOV that came with the UICP and replaced it with the HKS SSQV and now my boost, at the same setting, is 24PSI, hit fuel cut. Must be a leaky 1G BOV.
