Where are all of the Protege people running big injectors? The only one who had balls to come on here and tell it like it is was Terry. Other people have also posted that they have had problems with running bigger injectors.
It is very hard to cut down the injector duty cylce and still keep a good spray pattern. As the spray pattern get screwed up the idle will also get screwed. This is not opinion thtis is facts. How far you can cut the duty cycle is the game that you have to play. From cold start, idle, part throttle and WOT. you have to play the game.
I have used and still use big injectors on some cars[not the Protege]. They all of a trade off. With the extra injectors you do not have any trade offs. You get the best of both worlds. Maybe I will be proved wrong. Lets see if the AEM PnP does ever happen and if it runs right with the 550cc injectors.
Thanks again
