Yup.
I bigger IC will take more air to fill before beginning to build the pressure that is boost.
OP, think about the extra volume of air that is needed to fill the new IC, including any piping, etc. If the same turbo is working to fill that space, it will have to work harder to build the same amount of power. Let alone, to build more power.
Also, IC doesn't make power. It is a support part that allows you to run a larger volume of air.

Chances are the car would run like shit if there was a boost leak. Especially with the closed system and multiple German sensors looking for that sort of thing.
