But will jump back to 1200 after5 seconds. Then will repeat the whole scenario. Checked for vac leaks but can't find any. Did the throttle body reset for thinking it could be the new manifold.

Is it just the tune? Any other thoughts?
Hey TopgunZ

Look even at this part:

The small tube leading from the plenum to the BOV.
If the hose is detached or broken, then it may lead to this behavior.

My thought...
