try going into the settings and axes graphs

choose the one for thrust and make sure that the game is reading the input.
I would also check to make sure that it is calibrated in windows and that you are reading an intermediate input.
You can adjust the in game read to make it more or less sensitive along with the nice ability to create a "dead zone" between 100% and boost. Make your zero to 100% range really large to help get the resolution you need on the throttle control.
