Dead time setting sticks XBOX 360 controller.

There is one XBOX 360 controller. Use it on your PC. Recently changed him both the stick, because the old ones came loose. Now, on the new sticks a huge dead zone, that is, that the character in the game started to move very much need to move the stick, which is very inconvenient. I was poking around in joy.cpl but no effect to no avail. Question: is it possible to increase the sensitivity of the sticks or a feature installed tics and can only accept?
