Need help with Profec Spec II vacuum line install?????
I just purchased a Greddy Profec Spec II and I'm confused with the vacuum line installation. The instruction seems to be off. I have a single with a HKS wastegate. Here's how I ran the unit...
1) vacuum line from boost controller teed into fpr
2) vacuum line from top for wastegate to "COM" port of soleniod
3) vacuum line from side of wastegate to compressor side of turbo.
4) Put a tee in between the vacuum line in pervious number (#3) and ran a line from the tee to the "NC" (side port of solenoid) port on the solenoid.
The car is having problem making boost above 10 psi (10lb sping).
Am I running the vacuum line right????
