I have a 2001 GTS with the Nitrous Express Stage 1 kit. I have it jetted for the 35hp shot for the first bottle. After that I will bump it up the the 50 shot, no more. I've already sprayed about 10 times. A couple from a stand still, and the rest while already in motion. It's the best. It's hard to even retain traction with the 35 from a stand still. You can't beat the bang for the buck. I was originally going to purchase the XS Engineering kit, but that's never going to come out. Furthermore, the SCC Matrix detonated. Anyway, its a great system. Get it.
