Ok, I have xs T04E kit installed on my car, and add a profec b. But can only boost at 7psi. Assuming that is how much the wg springs is letting me boost. Where should I start looking to find out what's wrong? Everything looks like it has been hooked up correctly.

Any suggestions? I need help!!!

 

how much boost do you get without the profec b hooked up at all? Just running the hose from the intake pipes down to the wastegate?

B

 

getting 7 psi also

 

I just installed mine too, Im having the same problem. The instuction manuel was confusing. Im using a greddy open wastegate, and I noticed that there was another hole on the side of wastegate for another adapter(whats it for?).. I used the diagram that said "wiring-piping diagram extenal(poppet valve) type" .. All the others had "internal" .. I have hose going from the wastegate to the out part of the control motor. I have the hose from the intake man going to the "in" part of the control motor. I have the hose coming off the pressure inlet(controller) with a air filter going to the 3 way joint that connects to the fuel pressure regulator and hose from that to minifold.
The controller lights up like its supposed to, so it hase power running to it. My line have a lil slack in them because I didnt want to cut any rope that might need if it didnt work(maybe my problem)..

 

heres a good diagram..hope this helps you!
top port of the wastegate goes to the "OUT" port on the solenoid

 

thanks a-spec, but there isnt a pressure fitting on my turbo(greddy t-78 kit)(sorry i didnt mention).. There is a hose coming off the waste gate to the manifold(not the top nipple, but on the side.) The hose was allready there before I tried to install the bc. AmI supposed to do something with it???

If you don't have the pressure fitting on the turbo, use the extra nipple on the UIM on the side. It should be plugged off with a little black rubber thing. That would be the same.

For my case, the person who installed my single the first time, didn't install my wastegate properly. So it was alway open a bit. Fooked up thing about it, the first guy suggested I plump my wg back into the mp. That was some what of a patch for his halfass work. I couldn't tell all this time since it was plumb into the mp.

So Ivan, who is now working on my car messed around with it and reseated the wg. He said it's working now. But I still have pressure leaks somewhere else and he's fixing it. I'll let you guys know how it turns out.

 

All of the nipples on the UIM are being used. I only have one 3 way joint, so my options are limited. I still dont understand why the damn thing isnt working. I have a hose coming off the wastegate to the box and a hose coming off the box to the UIM. Why doesnt it work?????
