it's just that the change you make "fixes" the other flaws with the engine, and makes it work as it should
bit like mapping, when you map an engine, you don't create power, you release power thats already there as potential
I disagree with that, as of course you're gaining power from the increase in capacity, as all an engine is is an air pump. The bigger it is, the more it can pump. Obviously you have to make sure that there are no items on the pump restricting it's input / output, but if these are matched to the flow capacity of the engine, then power WILL go up with capacity increase

.
You'd have to be pretty stupid to increase the capacity without taking advantage of this increase with improved in/out additions.
