Better response is not the same as more BHp. At the end of the rev range, where the spec. sheet BHp is measured, there won't be a significant difference.
However with a remap, adapted to take all these mods into consideration, you will see more gains than you would without them. Although I have to say that the comments I've seen elsewhere on the forum lead me to believe the intake mods aren't worth anything for a road car.
