Can anyone post pictures of the installation diagram and instructions on how to install this boost controller, because a friend of mine just bought a car with this boost controller already installed and the car only boost to stock boost no matter the setting.

I don't know how the car ran before he bought the car or if it ever boosted more than stock, but whoever had the car before him looked he did a hack job with the vac hoses.

another question- is the soleniod suppose to click all the time on this boost controller?

Thanx in advance to anyone that could help me.

I've got a greddy profec b. The install is quite easy, but I don't have the diagram.

The power wire sounds like its hooked up correctly.

One vacum line is supposed to be tee'd in between your fuel pressure regulator and manifold. However, I tee'd the back line that runs to the stock boost pressure sensor, as that makes the line much shorter. One of the vaccum lines goes to the wastegate accutator, I think its the one that says ON on the solenoid. The other goes to the little nipple on the compressor. The harness for the solenoid should be plug in.

yes, the profec A (old school design) is a bit loud and clicks when the key is on. For the first drive, I thought I suddenly developed some valve ticking. ;) I also did an install write-up that may be of use a while back on supraforums: http://www.supraforums.com/forum/showthread.php?t=147430&highlight=profec


Greddy took down the diagrams because it is an old design, but the "wayback machine" has it archived: http://web.archive.org/web/20030215135958/http://www.greddy.com/Technical/profec_frame.htm
