this is simple and useful about injectors
i was reading up on injectors as i wasnt quite sure about some area's and found this, is fairly simple and informative, thought i would post it on here as some other may find it useful 
Please be aware of the fact that injectors cannot be replaced with other types (other flows) without also changing your engine-management and boost levels. If you simply try to do so you might end up with a very rich or lean running engine which will damage it.
The flow determines pretty much what maximum power can be obtained from your engine. With the flow percentages supplied by Graham Goode Racing the following (theoretical) power figures can be calculated:
Weber ??? (YELLOW, standard on 2WD): 100% flow, maximum 280 BHP
Weber 1070/00 1W-044 (DARK BLUE, standard on 4x4): 100% flow, maximum 280 BHP
Bosch 355 (VERY LIGHT GREEN as used on GGR 4x4 Stage 2 kit, ): 118% flow, 1.18x280=330 BHP
Bosch 803 (DARK GREEN): 135% flow, 1.35x280=378 BHP
Bosch 400 (LIGHT BLUE): 187% flow, 1.87x280=523 BHP
Bosch 403 (DARK GREY): 204% flow, 2.04x280=571 BHP
