If so, your MBC is fine, leave it. Your focus should be on those gashes on the UICP (upper intercooler piping). You have a boost leak. Any leak on the intercooler piping is considered a boost leak and any leak on the intake manifold is considered a vacuum leak.

You could be losing that 1 hg from the UICP. You could have a loosely seated throttle plate or the vacuum line going to the bov is leaking from the gash, through the bov. That''s a really minor issue. Deal with that gash and you will once you get a new UICP for the new bov.

Use the coarse knob to get the pressure set...

The fine tune knob isn''t used to get the desired psi, bro.

Bro, before you adjust the MBC any further, read the instructions. You''re doing it all backwards.

i was orignailly doing it the right way. i used the coarse screw to get boost and fine knob to tune it. and i read that directions 1,000 times. and did exactly what it says. i notice a diff when i back the screw out but not a difference when i go in? could it be stuck. when i blew into it with the screw all the way out it would blow air threw and then stop regulate it. when i turn it in a about 1/5 the way maybe 1/4 and i blow threw i get no air coming threw at all. ??
