Default New setup but problems BOOST will not stop climbing. 16PSI

Well i got my new stuff on no thanks to the guy i bought it from told me this was mocked up but it was not. or he mocked it up on a 1.8L and not a 1.6L.

But i do have a major problem. I think my Profec is hooked up wrong to the wastegate or not working at all. I mash the gas and boost just climbs. High boost bamn 16psi on the gauge i pretty much ---- my pants. Then i turned it to low boost and bam 16psi. After messing the the gain and balance some i went ahead and turned the profec off, Thinking it will just run off the 6 pound spring. I mash the gas and bam 16psi at about 7000rpm and it was still wanting to climb. What could be wrong?


here is the black box OUTLET circled


Now the outlet goes to the back side of the wastegate


then the vacuum hose from the top part of the wastgate goes into a "T" from the BOV to the vacuum block





here is the main picture color coded to where things are going



Any thoughts? comments?

try hooking up the bottom nipple on the wg to the compressor just to make sure the wg is working. that will boost whatever the wg spring is.

why not just keep ur foot in it at 16psi?

LOL steve cause Dave has not tuned it yet. last thing i need is to break something else. I will let dave do that :P Steve there is not a spot to hook up a vacuum line to the turbo at all.

just to note as of right now i only have the 5.8psi spring in it. the 14.5spring is in the box.

just use any Vac signal if its str8 off the plenuem ull prob get 1-2ish psi more. so just hook the bottom nipple to the vac log really quick to see what the boost is at.

I would be willing to bet its your wastegate dump recirculation that is making it creep. I saw a picture of it in the other thread and it looks bad.
