would have to say ATI Procharger....but you also need some type of timing control with it . Then Vortech is next in line . I dont know about Stillen , it maybe easier than both

I vote Procharger, if you watch Tuner Transformation on Speedvision, this weeks episode is a 350Z that gets a ATI kit. It dyno'd at 350some hp. They pulled timing some how with the stock ecu. Altered Atmosphere did the installation. The fuel is tuned with sliders like a audio mixing board. Kind of cool.
