after installing everything i set the mbc to its lowest setting and took it on a run. i hit 8 psi according to my boost gauge. i pulled over, turned it up, ran again and hit the same. so i turned it all the way up. yet again i hit 8 psi. there has to be something rong here because stock i was running 12 psi. so i switched the hoses around on the mbc and got the same result. i double and triple check my installation and it is correct. ### is goin on??

thanx jon

I remember reading a post on this style mbc, there was an issue of it not working properly & because of the design it shouldn't be run on our cars (have no idea why now). Personally I ditch that POS and get a good mbc that you know will work, the new JoeP IL mbc works great and is like $45 shipped, plus they have great customer service. Its a ball/spring design, very compact & doesn't require any tools to adjust.

here is how turbosmart tells you to hook it up it is the same basic setup. http://www.turbosmart.com.au/pdf/FG-GBCV-IC.PDF

Unless the arrow is on the wrong way in the first posted pic, the origional poster hasen't hooked it up the same way. In the linked instructions, the back side of the arrow is the source, the arrow points to the actuator & the last port connects to the controller (on the "T" fitting). He's got the "T" inline with the bov. What do you have hooked to the WG actuator?, looks like the adjuster part outlet, which is incorrect according to the turbosmart instructions.
