Have not used them on the 1000. I have them on my 600, didn't notice huge difference.
But essentially it depends on what you are looking to accomplish. Velocity stacks are not simply a power adding device; they used to tune the power band to what your specific needs are, hence why they make them in varying lengths. Shorter stacks lose some low-midrange power in order to give a slight increase in top end. Longer stacks do the opposite. So again, it depends on what compromises you are willing to make.
And yes, you need to retune the fuel map when using them.
