It has also been linked to poor vacuum pump performance to activate the turbo.
Also as has been said pressing the accelerator input pedal too fast will slow down acceleration. I think I precharge my accelerator slightly before I'm ready to accelerate. It was so much second nature I don't really think about it.
On the XC60 I often use the indicators to get instant acceleration. (they are linked to computer if you have adaptive cruise control)
Remember the accelerator is an electric input device to the computers giving them an instruction about what you want. Not a physical link to the engine fuel system.
