hey i have a question about the greddy profec b II......... i turned my hi and low both to 0 because i couldnt get it to work.... but it still doesnt work... instead of holding it to stock like it should, it boosts all the way to like 20+ psi... the only thing i can think of is that one of the holes on the control module thing is open.( the thing where two hoses goes into and the wires come out) i have one that goes to the wastegate and the other to my bov... i donno let me know if anyone knows whats goin on thanks
 
You say that you have one vac line going from the control valve to the wastegate, that is correct. But is the line going from the control valve to the bov t-ed into the vac/boost supply from the intake manifold to the bov or is it just plugged into the bov?

Sounds right to me..... also make sure you pull out all the plastic caps. I ran like that for a day before I actually read the manual. Its a good idea to give the thing a good once over.

where did you mount the selanoid?
 
yeah its T-ed into the intake manifold, but on the control module, there are only two vacuum lines going into it, there is still one side empty, its just an empty hole, and what were you talkin about plastic peices? when i mounted mine i just have it ziptied to my braided radiator hose----sounds ghetto, but doesnt look too bad, but neways nemore help would be appreciated thanks
 
I mounted mine where the stock one was.... seemed like a convienient location. There should be one empty hole (without a plastic cap on it)... one line that is Ted into VAC at your blowoff or wherever (no real need for a ton of extra tubing) and then the other end should go STRAIGHT to your wastegate. If it is Ted into the intake pull out the T.... go straight selenoid to gate, and plug the hole in the intake.
 
so it sounds like everything should work?i got one T ed with the bov and intake mani and the other to the wastegate.... but when i put a psi or whatever that i want it to hold at for either hi or lo, it boosts above 20 psi.. i even set them both at 0, still 20+ psi.... whats the problem
