for the hose that you splice into when connecting an MBC in-line with the n75 valve....anyone?

Any vacuum line should be fine...

Nevermind...I was thinking Boost gauge line.

Huh ? I didn't splice any hoses when running a MBC in parallel ..

How does that work with no splicing??

T connector on the OEM lines, then used some additional vacuum hose to run the lines to the MBC and N75 respectively.

Maybe I'm confused and don't understand what he is asking .. So you guys actually cut into the gray stock (boost and wastegate) lines ?

Maybe he is talking about the FPR line or something for a boost guauge ? That vacuum hose is avail from any Audi/VW part dept.

had to cut somewhere.....right???

I used the T split the charge pressure, one runs to the N75 and the other runs to the MBC which is mounted on the firewall, I used the Y to split wastegate line, which is connected to the N75 and the MBC.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1594286.phtml">https://forums.audiworld.com/s4/msgs/1594286.phtml</a</li></ul>

I added hose and connectors, instead of splicing into the OEM vacuum hose.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1584287.phtml">https://forums.audiworld.com/s4/msgs/1584287.phtml</a</li></ul>
