The Turbo Mode (F10 key) allows the timing of keystrokes to be adjusted to perform faster with certain games when held so you can speed up the rate of fire, etc. This feature may not work with all games, and you will need to test the different timing options to find what works best for your game. To use Turbo Mode you need to enable the primary setting on the Device tab, then also activate the Turbo function on the key you want to use such as the right trigger in the game profile. A selection wheel of timing options will be displayed for you to choose from and then press Save. If the first timing option does not work with your game or particular gun, remember to try other options. Also remember that setting the timing too short may stop other functions that use that button from working in your game so make sure to test thoroughly.
