How to open DV with N249?

When ECU wants to open DV durnig full throttle/acceleration, simply “energizes” N249, which will “de-select” the DV from the intake manifold (boost), and “switches” it onto the vacuum reservior. The vacuum in the reservoir will open the DV instantly and release your boost, which, in most of the cases (tuning, etc) is not that highly required .
