Saturn offers a stage II kit for the Redline Ion that consists of 4 injectors, an ecu reflash, a smaller pulley, and a new belt which brings it up to 246hp. This costs just under $1k for the parts (I know this because I work in a Saturn parts department). It's not much of a stretch to think that you could get a further 40hp from that like they are claiming, especially once you put all the stickers in. Something to think about: The driver was holding the camera, so who was shifting? Probably an automatic. I suspect the Z was an NA auto car, which = super sluggish.
