Why are you running both a CBV and a BOV?
Pick one.
Block the other off. Make sure if vented to atmosphere the BOV is shimmed/adjusted fairly tight. You can't have it open under any condition then 25-30" vac.
Hey Doug, been a long time...yeah, there's a Forge block off plate installed on the turbo as shown in the second photo. We just tried the cbv and bov together temporarily for troubleshooting purposes, and it made no difference. If the bov blows off any more than just a few psi, the engine will stall every time. I have a few cold side pipes, so if I remove the pipe with the bov on it, and replace the block off plate with the cbv, everything works perfectly again.
The most vacuum I see on the gauge is about -11 (psi/hg?)
