I can't get my mbc to work right. Here's a pic of the way I have it. Let me know what I'm doing wrong.
Thanks

Tee into the vacuum line between your bov and intake manifold. That goes into the nipple on your mbc across from the knob. Run a vacuum line from your wastegate actuator to the other nipple on your mbc. Block off the nipple on the lower intercooler pipe.

Well the boost is still going way to high. I usually cut out about 15 but it will go higher then that. Ok, here is a pic of what I have now. Also attached is a picture of where I have my boost guage. Is this the right spot?

put the boost controller in between the wastegate nipple, and the nipple on your lower intercooler pipe, right were it connects to the turbo. As for the boost guage T into the vacuum source that comes from your intake manifold, I cant see the pics so thatts my best advice. Trust me on the mbc.

You now have input from both camps. I'm of the use the turbo outlet nipple camp vs using the BOV line. Since you have connected it both ways and still have problems you need to start looking at if your MBC is working correctly or if you have wastegate caused boost creep.

I connect the boost guage to the line from the intake manifold to the fuel pressure solenoid but you can use the "P" port on the throttle body. As long as you see both boost and vacuum on your guage you have the right tap.

I've tried both the bov line and the turbo inlet. In the process of doing that I elimated the turbo waste gate solenoid. The car stutters now after trying the turbo inlet.
The reason I ask about the boost guage tap is because if I hookup at the p-port I get 14. If I hook up at the fuel pressure solenoid I get around 18. Thanks for you help guys.

not to be an ass... but from the pics, it looks like the screw on the mbc is all the way in... again, not to be an ass... but you do know that in = higher boost, right?

That is pretty close to all the way out.
