Having an issue with post Boost stall.Boost set @ 6PSI. Does anyone have an idea what recirculating or diverting valve can be used with this engine.

If you are still on CIS, wouldn't it be easier to add a dashpot to the throttle stop or to raise the idle speed a bit? Your management has no ability to control a recirc or divert valve. What about a blow-off valve?

HI Happy Easter I have a Blow-off valve that is presently adjusted to max Blowoff. I'm thinking if I re-adjust the setting to minimal blowoff the back pressure to the Turbo will prevent the Post Boost stall. The idle speed is presently 1000rpm. Engine is a 2.0l 8v with Callaway Turbo

CIS, Digi, standalone like MS....sounds like a tuning issue.
