I haven't heard of drops that big, but I have heard you do drop boost. You are reducing the restriction in the flow path, so boost isn't as high to flow the same amount of air.

you would think boost would go up due to the extra air going into the motor my boost stayed the same with my monster cam

Good testament to a better flowing cam.
Pressure and flow are mostly opposites or an inverse relationship. Higher pressure is lower flow and visa-versa.
