It depends and I know that sounds dumb. Look at basic hydraulic principles and you'll understand further how it will have an effect.
The smaller the MC bore the higher the pressure but smaller the volume. The larger the MC bore the less pressure but more volume. Now on the other end of the line the larger the size of the wheel cyl the higher the pressure exerted because there is more surface area exerting the pressure.
