Bs3 seems to work pretty well for the world's fastest street car. I'm not saying there isn't a lot of great stuff available on the market today, but I would definitely say a used bs3 or fast xfi system can be a very good value.
If purchasing new I personally would take a good look at the haltech elite 2500 or the fueltech systems myself.
