stand alone fuel injection system
it completely replaces your stock method of injecting fuel. most stock systems have low limits, because of sensors or the actuall computer installed.
Stand alones replace the brains of the injection system.. they can be used as a replacement for stock injection to get more power and when running odd combinations of parts.. drivability.. or in a case like my ancient (or as the state calls them, antique) sports cars.. you can use them to add fuel injection to a previously carbed car
Tibby01 got it right though.. most comps in modern cars are not tuned for power.. but for low emissions and economy.. not bad things for 98% of the people who drive. However, those same parameters that give good fuel miliage and a squaky clean tailpipe also inhibit ultimate power... For a daily driver, unless you are going from carbs to injection.. I would not bother.. for a car that sees half it's life or more on the track.. it is a necessity.. becoming more and more urgent the more time you car sees the track as opposed to the street.
