Landing Boost
Landing Boost can be performed with the "Landing Boost" tuning part, which is an Epic tuning part that can be obtained on all vehicles except Monowheel and hoverbike, equipped by usually ensuring the vehicle lands from an at least 1 second long jump with all its wheels (or the 2 front wheels for moonlander) touching the ground almost simultaneously. Successfully performing this move will be signified by a sudden "dash" of speed by your vehicle, as well as a discharge of sparks from the wheels and a distinctive sound. If you combine it with "Jump Shocks" and activate them at the right moment, it will give you an upwards boost and you can increase your momentum for a longer time by perfectly performed jumps. Landing Boost can be used even after running out of fuel.
