Nice work Tas. Have you thought about changing 5th gear to lower your rpm? Your Jetta looks pretty aerodynamic so you may not need as much power at highway speeds. I just completed a belly pan (new thread coming soon) and it seems to be helping. I have a very steep driveway so I can't really add air dams.
