Touched Event Delay, Help?

When the script runs in test-mode (client) it runs as expected. When the script runs in a game, the onTouch event proves to be very delayed from the time the rocket hits the object to the time it actually explodes. Here's the code that makes the rocket explode:

script.Parent.Sound:Play()
debounce = true

script.Parent.Touched:connect(function(part)
	
	if debounce == true then
	debounce = false
	local explosion = Instance.new("Explosion")
	explosion.Parent = game.Workspace
	script.Parent.Explosion.PlayOnRemove = true
	explosion.Position = script.Parent.CFrame * Vector3.new(0,0,-script.Parent.Size.Z/2)
	function ExplosionHit(part)
    if part:IsA("Part") and part.Anchored == false and part.Shape.Name == "Block" then -- you can also use just the objectvalue of the part
       part.CanCollide = false
    end
	end
	local creator = script.Parent:findFirstChild("creator")
	
	function tagHumanoid(humanoid, creator)
	-- tag does not need to expire iff all explosions lethal	
	if creator ~= nil then
		local new_tag = creator:clone()
		new_tag.Parent = humanoid
	end
end

function untagHumanoid(humanoid)
	if humanoid ~= nil then
		local tag = humanoid:findFirstChild("creator")
		if tag ~= nil then
			tag.Parent = nil
		end
	end
end
	

local humanoid = part.Parent:FindFirstChild("Humanoid")
tagHumanoid(humanoid, creator)
explosion.Hit:connect(ExplosionHit)
script.Parent:remove()

  end
end)
