i am considering adding nitrous to my car. i am probably gonna just go with a small 75shot. i will only use it at the track, maybe once or twice a month. what kits do you guys recomend? i hear the words foolproof when talking about a lot of the kits out now, how true is this? how safe is a small shot on a 99 and up GT? and how well will it work with 4.10's? i know i want a wide open throttle switch, and a window switch. also my car is an automatic, i am not sure if it matters at all.
