i went around messing with it for a little while and i turned the balance **** to the center and ran the car on low boost setting with the boost **** all the way to the left i had stock boost 5psi....then i started turning it clock-wise to increase boost and went almost 3/4 of the way to the other side and didn't really see anymore than 5psi.....any helpful hints on messing with the profec b?....or ideas that i coud check? here's my set-up:
zc motor w/92-95 greddy kit
fmu
310's inline pump
internal wastegate

-please post any suggestions

 

anyone ...????

 

Check the contacts to the black box and to the wg, perhaps you are loosing pressure from the lines.

Try it again.

The balance **** is on 12, right?

 

yeah it sounds like your profec is connected up wrong on the black port and wastegate. you'll definetly be able to see a boost change.

 

hose from comp. housing on turbo to the in on black box...and the out to the wastegate acuator ..?is this right ?...also i had the balance on 12:00 but if i turn it to the sharp directio it doen't make much change

 

I had the same problem. I had a hose going from the compressor to the bottom of the BOV (per my instructions). All I needed was to remove it and everything worked. The HKS BOV only needs the top port plumbed to the manifold (so vac will open it) the other is open to air.
The compressor nipple feeds a tube to the inlet on the Greddy box and the out goes back to the SIDE of the wastgate. The wastegate only needs pressure to this port to open it (the other is open to air).
