I installed my Buschur MBC from my IX on my MR and I am having boost issues...

I can hit 1.5 bar in 3rd, but it quickly falls down and holds at .7 bar...Now it's ENTIRELY possible I have the lines backwards Since I didn't keep the install instructions, can anyone that has the Buschur MBC tell me which line goes to my turbo and which line goes to my wastegate? I have it mounted on the battery screw-down post, so the top nippe comes out the side and the other nipple comes from the bottom.

 

why don't you connect it to the other way and find out.

BTW, there is a "how to" for a hallman MBC.
You can use that for refrence.
I have the boost source connected to the turbo nipple.

 

Buschur instructions:
The part that is on the knob goes to the boost nipple off the compressor housing to your LICP pipe.
The part off the nipple that is in the middle of the valve goes to the wastegate.

If it was backwards you should be getting tons of boost. And very irregular spikes too.

 

OK, thanks Joe...that's what I needed.

I had it right, so I must have a leak somewhere.
