I recently switched from a Thrustmaster T500RS setup to Moza with USB pedals from a different brand and mapping the W button to the throttle using joytokey I noticed that the W button does not represent 100% throttle.  Some vehicles will move and others will not budge unless using a mod with a OP engine.  I know this doesn't make sense but could this be looked into.  I don't need fine controls for the throttle, just fully on or off is good for this game.  Same issue with the brake as well.
