It basically makes the range of 0% to 100% throttle happen over a smaller range of throttle pedal movement.I've never felt the need before on other VAG cars...but the Mk6 GTI has tragic throttle response.The sprint booster makes it possible to blip the throttle without feeling like you are going up stairs...and makes the car far motre lively.sure, you can get the same affect by pressing the pedal further...but try doing that whilst heel-toeing.It can't open the throttle any further than the TB allows...so no damage can occur. It doesn't affect enough for that to happen.
