Message	excursion! it idles fine with the 720's, it will definitely be richer though... just not as smooth as stock ones, and just slightly worse than 555's. at idle, it's not really the same amount of fuel. the way injectors work, the pintle is open for x amount of milliseconds to allow y amount of fuel to flow. so, if the opening is bigger, then the pintle has to be open for a shorter amount of time to allow the same amount of fuel through. the shorter amount of time, means that the ecu has to have better resolution in order to accurately control that fuel... so, basically, the longer the ecu has to control the injector, the better it is in terms of accuracy. 720's will have a shorter open time, so it's less accurate and thus idle and gas mileage get hurt... but, it's still definitely streetable... don't listen to your friend. : die all time... : i am getting the dual pop chargers along with that... : but he says the extra fuel is gonna kill it all the time and my gas mileage will go to worse than a ford Excusion when i'm babying it; it didn't sound right to me... same amount of fuel is flowing either way Bernie The heart of the Phoenix... bhsiao@newssun.med.miami.edu
