I purchased a Dejon Tools MBC after hearing it recomended by so many around here. I installed it just as directed in its instructions and per this post here:

Before the install I would hit 20psi of boost and hold 18-19 just fine. Now I hit 19psi of boost and don't hold sh*t. I am not sure what is going on, but I have tried turning the thumbscrew in and nothing has changed... Any ideas?

I have the tube FROM the vaccum line at the BOV connected to the inlet on the MBC directly opposite the thumbscrew (bottom) and I have the nipple out the side connected directly to the wastegate. I did not use their connector with the hole drilled in it. I capped off the turbo nipple and the one on the intake tube.

Whats going on here? Do I need to use the fitting with the hole drilled in it? I didn't see if used in the writeup? Wuld that really make a difference?

 

I see it in the writeup now... I wonder if thats my problem...

 

hmm reading the isntructions it sounds like it may be. What a dumbass. I'll go install and try again.....

 

Yup. Dumbass award here!

I will leave this so if anyone makes the same mistake of not following the instructions they can read it and not feel all alone in their stupidity!
