I have 1 used Greddy Profec B Boost Controller. Its the model with the three ***** (low,hi,gain). I used it for about 1 year and I recently upgraded. When I took it out it was having trouble holding boost I dont know if the selenoid was going bad or if it was hooked up incorrectly somehow, or if it was a vacuum leak...etc.. Comes with control unit, all wiring, and selenoid. Since Im not sure if it works perfectly 100% im gonna say ill take $100 shipped.

pm me if your interested. I have a few vouches if necessary.

 

free bump . Were the settings right on the back of the controller?
