venom nitrous kit

does anyone have any experience with the venom kit for camaros? are they truly any safer than just running a traditional nitrous kit such as NX with the TPS sensor and window switch?? What is the difference inbetween the VCN-1000 and the VCN-2000, besides the other 2 modes, (besides drag mode), that it can use that I have no intension of using?? I visited the venom website but they dont make a whole lot about there kits to clear, how does the VCN-2000 even work, they make it seem like they dont use nozzles for the nitrous on it.....

Also, i plan on running a head/cam package on top of a 100 shot of nitrous, so i'm not so sure how well this kit may function with a modified pcm, does anyone know?
