Um, huge no.

The brake booster line is always under vacuum. At full throttle that vacuum level goes down, which lets you use that same line for the bypass actuator. If you tie in the Manifold Absolute Pressure sensor into that line it will only see vacuum, not the absolute pressure in your manifold. Engine go boom as it goes super lean under boost.

Connect the MAP sensor to the nipple on the back of the supercharger (after the scrolls where boost is present) that used to connect to the actuator.
