Stock software, you might just feel like the car is running smoother.
GIAC software, you notice some power increase too.
APR I have no experience with, but I imagine you would notice a power increase as well.
Depending on the software, you can take some advantage of the increased stability in higher octane fuel.

If it does on pump fuel then you will gain some power while runing better fuel, if it does not pull any back then you wont gain much at all.
