Greddy Profec B not controlling boost

NickSTi · 07-04-2002, 05:19 PM

I am figuring there is something wrong with my vacuum line to my wastegate, I have to find a lift to look at it, but i hit 1 bar

First question is, who are the selectors in the back supposed to be set? On their website it says there are actuator and external settings. Right now I have it set as
- _ _ -
1 2 3 4

(for those who have a profec... u understand)

It still didnt work. I have the balance at 12 o clock. and the low selected and all the way to min.

Any ideas?

IIRC , you're supposed to have to have a vuccum line going to the back of the unit . also if you have boost spikes , the pdf file on their site tells you which of those settings in the back to change . Do you think you have the installation correct ? if it doesn't hold boost at all then it could be that something isn't hooked up correctly.

i think those 600 horses are going to your brain z

that was more or less what i knew, that the vacuum line to the wastegate is prob not right. But i checked and saw nothing wrong. I looked on the site and that was where i saw the settings on the back. The funnie thing is i have it on min and i am seeing too much boost.

I will do some hose checking now. but i dunno.

Thanx tho.

Nick - Check your PM... I was wondering what the rate of the spring is in your wastegate. Also, if you hook it up straight from manifold to wastegate with no disruption, what kind of boost do you run?
