930 bypass valve thats not open @ idle/low speed?

The C2 turbo bypass valve sucks unmetered air @ idle. Is there a good aftermarket valve that stays closed @ idle and low rpm unboosted cruise, and opens with higher vacuum on higher rpm closed throttle shifts? My '87 project.

Probably no one else here has that car!

I don't know what the intake arrangement looks like, but can you set it up like modern audi/porsche/vw products that port the bypass into the intake after the air meter?

Can you put a check valve at the outlet? Won’t let the idle air in but will let the boost dump air out. I use one for an inverse problem where I let idle control air in but not boosted air out.
