I just got my Profec B and it looks easy to install,But my question is what is the port on the back of the control unit for?It says pressure in,Under it.What do i do with that?-Thanks,

I posted this in tech section but i seem to get better results with the RWD forum.So if you see it twice thats why.

Is it a nipple? Its probably for a vac hose, it reads boost just like a boost gauge. You have to T off of the vac hose that goes from the throttle body to the fuel pressure regulator.

Not to be a smartass, but if you read the instructions it tells you exactly what everything does and how to hook it up and set it up. I know this because I installed the same controller about 3 weeks ago. It was the first time I had ever done anything like that, so believe me when I tell you the instructions make it simple.

If you bought it used or something and don't have the instructions, here's a link : http://www.greddy.com/tech/PROFEC_B_SPEC2.pdf
