Since I finished my single install I have not been able to keep the boost down. I am running a T04R with a HKS standard gate. I have tried the two different ways to hook up the vacuum lines with my AVCR and a manual boost controller. Is there any maintenance that needs to been done? Or a preferred way for it to be hooked up. Any ideas would be helpful, thanks.

 

If you disconnect the boost controller and just run on spring pressure (just the pressure line to the side port, top port vented), do you have controllable boost?

 

I will try that tonight, thanks.
