How do I change the speed of this snowboard? (edit)

I looked everywhere in the script to see what affects the speed but nothing worked

local Board = script.Parent
local Controller
local Gyro
local CoastingAnim
local KickAnim
local LeftAnim
local RightAnim
local OllieAnim

local OllieHack = script.Parent:FindFirstChild("OllieThrust")
if (OllieHack == nil) then
    OllieHack = Instance.new("BodyThrust")
    OllieHack.Name = "OllieThrust"
    OllieHack.force = Vector3.new(0,0,0)
    OllieHack.location = Vector3.new(0,0,-2)
    OllieHack.Parent = Board
end

local lastaction = nil
local lasttime = nil
local jumpok = true

function didAction(action)
    lastaction = action
    lasttime = time()
end



function onAxisChanged(axis)
    Board.Steer = Controller.Steer
    Board.Throttle = Controller.Throttle

    if (Board.Steer == -1) then
        print("Left")
        --CoastingAnim:Stop(1)
        KickAnim:Stop()
        OllieAnim:Stop()
        RightAnim:Stop(.5)
        LeftAnim:Play(.5)
        didAction("left")
    end

    if (Board.Steer == 1) then
        print("Right")
        KickAnim:Stop()
        --CoastingAnim:Stop(1)
        LeftAnim:Stop(.5)
        OllieAnim:Stop()
        RightAnim:Play(.5)
        didAction("right")
    end

    if (Board.Steer == 0) then
        print("Straight")

        KickAnim:Stop()
        LeftAnim:Stop(.5)
        OllieAnim:Stop()
        RightAnim:Stop(.5)

        if (lastaction == "go" and time() - lasttime < .1) then

        end
        didAction("go")
        --CoastingAnim:Play(1)


    end
end

function enterAirState()
    -- gyrate towards vertical position for better landing
    Gyro.maxTorque = Vector3.new(100, 0, 100)
    jumpok = false
end

function exitAirState()
    -- turn off gyro
    Gyro.maxTorque = Vector3.new(0,0,0)
    jumpok = true
end

function enterPushingState()
    KickAnim:Play()
end

function onMoveStateChanged(newState, oldState)
    print(oldState)
    print(newState)
    -- do state exits here
    if oldState == Enum.MoveState.AirFree then exitAirState() end

    -- do state transitions here

    -- do state entries here
    if newState == Enum.MoveState.AirFree then enterAirState() end

end
