can injectors be too large?

[spider_slayer]

i am planning to upgradeing to a gt28 in the future. I have ordered a greddy emanage unit and now i need to choose a set of injectors. its about 500 for 555cc injectors and about 40 more for 740cc injectors. since i have a fuel management system i was wondering could any harm come from using the 740's on the stock turbo for the time being until i upgrade my turbo? i understand that to much fuel is a bad thing but i'm thinking i could keep everything running smooth with the emanage.

note: i don't have a spefic hp goal. i'm guessing i'll stop the upgrading once i hit 400whp

ok, so let me ask this.....what complications arise from the injector cycle being to low?

[ca18det_boy]

if its too low then they will not operate properly. So if the duty cycle is to high then they get stuck open and do bad things. If the duty cycle is too low then they don't open properly.
