You're right, the car it should accelerate the same way as a before, only it'll reach that high RPM quicker. That's the main performance benefit.

Which gear/rev range does it not pull as hard? Does it pull less? Keep in mind, this type of pulley will not create HP.

It's a crank pulley, Let me test it out some more and see what happens, it could be all in my mind... Also I have an automatic not stick, so that might be part of it too, but for sure my idle did drop to normal from this.
