member introduction/Boost controller Problems

[Zchef85]

I am a pretty new member to this site I live in sacramento CA and I love zcars I have had several over the past years and cant get enough of them

Maybe you guys could help me figure something out.

 

I have a 85 300zxt and

I recently aquired a turbonetics "VBC kit" But when I got it I realized that the directions were for an external wastegate (dual port) but I figured that the principles were the same , restricting the signal line to the wastegate via an inline valve with a knob attached like the one that came with the kit.

I noticed that the wastegate actuator gets its signal from 2 ports on the intake side of the turbo so i added about a 1-1/2 foot piece of vaccuum line from the compressor to the controller, then another line from the controller

to the wastegate actuator ok so everthing clamped down controller is set to fully open so that I should be running stock boost. So I take it for a test drive and the thing is running like 8 psi and opening the pop off valve when it should be running 6 and then I tried turning up the boost and it only made 6 psi, now i am throughly confused.

 

Is it the controller?, Do I have it hooked up wrong? Any Ideas/suggestions?

thanks A lot

if you still have the POV, you wont be able to boost it more than factory. i suggest taking it out and plugging it. if my memory serves me right, then its just a standard 1" plug. i got mine from a NA plenum.

That is the next thing I did, the problem was that when the boost should be stock it was hitting 8 psi and after i plugged the pop off vvalve it wanted to boost with no wastegate (it tried to go to 15psi at 1/2 throttle) then I added boost and it went back to 6 psi?. So what I am saying is when it should be doing stock its doing unlimited and when I try to add boost it goes immediatly to stock boost and I only want to run 10psi, I think my controller might be messed up...
